Advantages of Aluminum Nitride Powder

/ / no Comments

Aluminum nitride It is an aluminium solid nitride that has excellent thermal and electric conductivity. It has an excellent band gap of 6 eV at ambient temperature and is being used in optoelectronics. Below are some examples of its properties and their applications.

Very high thermal conductivity

Aluminum nitride is one of the newest materials in technical ceramics. It was originally discovered nearly a century back, but it is only now that it can be made into a viable commercial material. It can be used to make composite materials, and it is especially good at improving mechanical properties.
A material's thermal conductivity refers to its ability to heat transfer when exposed to temperature variations. Reticulular vibrations are also called phonons and aluminum nitride is capable of carrying heat. This property is common in materials with covalent bonds and low atomic mass. There are many factors that affect thermal conductivity. These include temperature, impurities and even the presence of heat.

Aluminium nitride exhibits high thermal and electric conductivity making it an attractive material for electronics. Thermal conductivity for polycrystalline AlN ceramics is between 17 and 285 W/mK. It is the process of sintering that determines the difference between single-crystalline and multicrystalline ceramics. This is what determines the microstructure of the material and its conduction mechanism.

AlN can also be machined to create complex shapes. AlN's high thermal conductivity is not only impressive, but it also has exceptional heat radiation and electric insulation. AlN can be machined to complex shapes, making it suitable for high-power electronic applications.

Microelectronics uses aluminum nitride as a standard material. The material's excellent thermal conductivity makes them a perfect medium to heat sinks or electrical insulators. The material can be used in silicon-based products because it does not react with many chemicals or gases.

Aluminum nitride (or aluminum nitride) is an innovative ceramic that has excellent electrical and thermal properties. The cost of aluminum Nitride is quite high so domestic production remains a problem. However, scientists are trying to resolve this issue. These developments could lead to aluminum nitride being a viable option for high-end semiconductor packaging.

It is the heat transfer rate between two materials. Thermal conductivity is the rate at which heat transfers between two materials. A single crystal has higher thermal conductivity than one with non-conducting. This is an important property in a semiconductor. It should be considered when designing a material for a particular application.

Electric insulator strong

Aluminum nitride exhibits excellent thermal conductivity as well as electrical insulation, which makes it ideal for high-powered electronic applications. This metal is a good choice for power electronics because of its similar mechanical and electrical characteristics to silicon. You can use it for microwave tubes or hybrid circuits. It is capable of being fabricated in complex geometries with no loss of its electrical insulating qualities.

Aluminium Nitride is a good material for high-frequency electronics as well as high-voltage devices. The semiconductor industry uses aluminum nitride as a substitute for Beryllium Oxide due to its low thermal expansion. Additionally, the material is safe to machine and it matches silicon wafers in CTE. It's a good choice for high-temperature electronics.

AlN offers excellent electrical insulation with a low constant dielectric, which makes it ideal for various electronic applications. Additionally, AlN's surface can be metallized in order to create thin films. These are great for electronics circuits, wiring bonding and chip mount.

Aluminum nitride has another property: it's stable at very high temperatures. However, at 700 degrees Celsius, the material oxidizes to form a layer of aluminum oxide. Although it is very stable in the carbon dioxide and hydrogen atmospheres, it does not dissolve quickly in water. Aluminum nitride's low electrical conductivity makes it a popular choice for electronics.

F. Briegleb & A. Geuther first synthesized aluminum nitride 1862. Aluminium nitride is superconductive under high pressures despite having a low density. This material also exhibits excellent thermal conductivity. These properties make it a popular choice for semiconductor devices.

Resistance to molten metallics

An aluminum nitride ceramic compound is resistant to thermal shock and abrasion. You can use it in many applications to prevent metals from corrosion and abrasion. It has particles sizes between 0.2 micrometers and 5 micrometers. The general rule of thumb is that a higher content will give you better resistance to abrasion.

Aluminum nitride belongs to the hexagonal glass system and is a covalent bonds compound. It can be gray or off white in color, and it is great for insulation materials. Aluminum liquid cannot penetrate it because of its high thermal conductivity. Aluminium nitride, however, has a low thermal conductivity as well as oxidation resistance. Additionally, it is susceptible to absorb moisture and undergo hydrolysis. Additionally, the temperature at which it can decompose is 2516° Celsius. However, aluminum nitride can be used as a metal of high quality that is resistant to corrosion and heat.

Aluminum nitride can be used to make stronger structural materials than alumina. Additionally, it has high hardness as well as abrasion resistance. But, it has lower mechanical strength than alumina and thermal shock resistant. It is not recommended for use in composites because of this.

The material also has good melting resistance and adhesion. Aluminium nitride makes a good choice when it comes to molten-metal applications. This metal can be used to make molten members. To avoid rupture, however, the member must exhibit good adhesion.

Protective coatings for foundries can be made from aluminum nitride. It's inexpensive and straightforward to make. It also resists corrosion. But, it may not completely resist molten aluminium. Additives may affect its ability to resist molten metals.

Aluminium nitride, in addition to being resistant to molten metallics has good adhesion properties and melt loss resistance. Aluminium nitride offers better adhesion and resistance to heat shock than aluminum oxide. Aluminum oxide has a tendency to fracture and crack. Additionally, the aluminum oxide has a weight of 90 wt. % of Boron

The product sintered was evaluated for resistance to thermal shock, melting loss, adhesion and molten steel. For ten minutes the test item was submerged in molten iron before being removed. A 4-point bending test was used to measure the adhesion.

Aluminum Oxide Al2O3 CAS 1344-28-1

/ / no Comments

About Aluminium oxide:
Aluminum oxide is an electrical insulator, it has a fairly high thermal conductivity to ceramic materials. The most common form of crystalline alumina is called corundum. Alumina can provide activated, super-activated, acidic, alkaline and neutral grades, and has flash grades, TLC, biomass purification, decolorization, dioxin analysis, PCB removal, pyrogen removal and biotechnology wide-pore forms. Oxide does not conduct electricity. However, certain oxides of perovskite structures have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, so they can be used in ceramic structures, such as clay bowls for the production of advanced electronic devices, and lightweight structural components used in aerospace and electrochemical applications, such as fuel cells. Exhibits ionic conductivity. Metal oxides are basic acid anhydrides, so they can react with acids and strong reducing agents in redox reactions. Reactive chromatography grade alumina is used in lighting, photographic chromatography and various chromatographic separation techniques. Alumina is usually available in most quantities immediately. High purity, sub-micron and nanopowder forms can be considered. Alumina can also be made into particles, pellets, powders, sputtering targets, tablets and nano-powders. Provide typical and customized packaging, as well as other research, technical and safety (MSDS) data. Please contact us for the above delivery time and price information. Feel free to send an inquiry to get the latest price if you would like to buy Aluminum oxide in bulk.
 
How is Aluminium oxide produced?
Aluminum oxide is produced by the bauxite process. The Bayer process is carried out in four steps. First, the bauxite is crushed, washed and dried, and then dissolved with caustic soda at high temperatures. Next, the mixture is filtered to remove impurities called "red mud" and discarded appropriately. The remaining alumina solution is transferred to a high tank called a settler. In the sedimentation tank, the hot solution begins to cool, and aluminum hydroxide seeds (very small particles) are added. The aluminum hydroxide seeds stimulate the precipitation of solid aluminum hydroxide crystals. Aluminum hydroxide precipitates at the bottom of the tank and is removed. Finally, all remaining caustic soda in the aluminum hydroxide is washed and heated to remove excess water. After this process, alumina (alumina) appears as a fine white powder. It looks a lot like sugar used in baking, but it is hard enough to scratch the glass plate.
 
Application of Aluminium oxide:
Most of the alumina produced is used to form aluminum metal. Oxygen usually reacts with metallic aluminum to catalyze corrosion. However, when combined with oxygen to form alumina, it forms a protective coating and prevents further oxidation. This increases the strength and makes the material less prone to deterioration. Alumina is mainly used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials.
Industries that use alumina include:
Medical industry
Due to the hardness, biological inertness and chemical properties of alumina, it is used for hip replacement surgery prostheses, bionic implants, artificial eye substitutes, tissue reinforcement materials, crowns, abutments, bridges and other dental implants. The preferred material of the bearing. It is also used in laboratory equipment and tools such as crucibles, furnaces and other laboratory appliances.
Military and protective equipment
The strength and lightweight properties of alumina help to strengthen body armor, such as breastplates and armor for cars and airplanes, which is its largest market. Alumina is also used to synthesize sapphire bulletproof windows and bulletproof systems.
Electrical and electronic industry
Its high melting point and high boiling point, as well as its excellent heat resistance, make alumina an ideal material for high-temperature furnace insulators and electrical insulators. Alumina film is also a vital component in the microchip industry. Some of its other uses include spark plug insulators, micro-electric substrates and insulating heat sinks.

Performance of Aluminum Oxide Al2O3 Powder：
Aluminum oxide (aluminum oxide), chemical formula Al2O3. It is a high hardness compound with a melting point of 2054°C and a boiling point of 2980°C.

How is AlN Ceramic Powder Injection Molding Components Produced? 
Preparation of aluminum nitride ceramic powders by direct nitriding of Al powder:
The direct nitriding method of Al powder is the earliest method to prepare AlN powder. In this method, aluminum powder is heated in nitrogen. At high temperatures (800~1200℃), aluminum powder and nitrogen directly react to produce aluminum nitride powder, the reaction formula is 2Al + N2 =2AlN.
This method has the advantages of abundant raw materials, low cost, simple process, and no side reaction. However, the disadvantages of this method are also obvious. At the initial stage of reaction, the surface of aluminum powder particles will gradually form a nitride film, which makes it difficult for nitrogen to penetrate further and hinders nitrogen reaction, resulting in a low yield. And because the reaction between aluminum and nitrogen is a strongly exothermic reaction, the speed is very fast, resulting in the AlN powder self-sintering, forming agglomeration, making the powder particles coarsening.
The preparation methods of aluminum nitride powder include Al2O3 carbothermal reduction, self-spreading high-temperature synthesis, high-energy ball milling, chemical vapor deposition, sol-gel method, plasma chemical synthesis, in-situ autoreactive synthesis, arc melting, microwave synthesis, sol-thermal synthesis, etc.
 
Applications of AlN Ceramic Powder Injection Molding Components:
1. Aluminum nitride powder with high purity, small particle size and high activity. It is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrate.
2. Aluminum nitride ceramic substrate has high thermal conductivity, low expansion coefficient, high strength, high-temperature resistance, chemical corrosion resistance, high resistivity, small dielectric loss. It is an ideal substrate and packaging material for large-scale integrated circuits.
3. The hardness of aluminum nitride is higher than that of traditional alumina. It is a new type of wear-resistant ceramic material, but because of its high cost, it can only be used for parts with severe wear.
4. By using the heat resistance, melt erosion resistance and thermal shock resistance of AIN ceramics, GaAs crystal crucible, Al evaporation plate, magnetic fluid power generation device and high-temperature turbine corrosion resistance parts can be made, and its optical properties can be used as an infrared window. The aluminum nitride film can be made into high-frequency piezoelectric elements and very large-scale integrated circuit substrates.
5. Aluminum nitride heat resistance, corrosion of molten metal, stable to acid, but in alkaline solution is easy to be eroded. Exposure to wet air on the new surface of AIN reacts to form an extremely thin oxide film. Using this characteristic, it can be used as a crucible and casting mold material for aluminum, copper, silver, lead and other metals melting.AIN ceramics have good metallization properties and can replace toxic beryllium oxide ceramics in the electronic industry.

Storage Condition of AlN Ceramic Powder Injection Molding Components:
The damp reunion will affect AlN ceramic powder injection molding components dispersion performance and using effects, therefore, it should be sealed in vacuum packing and stored in cool and dry room, the AlN ceramic powder injection molding components can not be exposure to air. In addition, it should be avoided under stress.

Scandium Aluminum Alloy Al-Sc Alloy

/ / no Comments

About Scandium Aluminum Alloy Al-Sc Alloy:
Al-Sc alloy is a kind of high-performance aluminum alloy. There are several ways to make an aluminum alloy with high performance. Microalloying hardening and toughening is the frontier field of research on high-performance aluminum alloy in recent 20 years. Scandium aluminum alloy is a successful combination of scandium and aluminum metal. Scandium is a silvery-white transition metal and is commonly listed as a rare earth element (REE) along with yttrium (Y) and the 15 lanthanides (La) elements. The alloying of scandium into an aluminum can increase the strength and desirable properties of aluminum. The addition of scandium restricts the excessive growth of grains in the heat-affected zone of aluminum welds. Orachemicals is a trusted global Scandium Aluminum Alloy Al-Sc Alloy supplier. Feel free to send an inquiry about the latest price of Al-Sc Alloy at any time.

Product Performance of Scandium Aluminum Alloy Al-Sc Alloy :

Aluminum scandium intermediate alloy is a high-performance aluminum alloy, which can not only significantly refine the as-cast alloy grains, increase the recrystallization temperature to improve the strength and toughness of the aluminum alloy, but also significantly improve the weldability and resistance of the aluminum alloy Thermal, corrosion resistance, thermal stability and resistance to neutron radiation damage.

 

How is Scandium Aluminum Alloy Al-Sc Alloy Produced? 
The preparation of the master alloy is the key to the production of Al-Sc alloy. The preparation method is as follows:
Preparation of anhydrous scandium chloride molten salt
1. Vacuum dehydration
Dissolve SC2O3 in hydrochloric acid, and mix SC2O3: NaCl: KCl: NH4Cl in proportion. Evaporation, vacuum removal.
2.Dehydrate at medium temperature
The molten salt after vacuum dehydration is heated under the protection of argon to make molten salt of ScCl3·NaCl·KCl, namely, anhydrous scandium chloride.
Preparation of Al-Mg-Sc master alloy
Industrial pure aluminum and industrial pure magnesium, ampere proportional heating melting. Adding SCCl3 ·NaCl·KCl molten salt, and specific additives, smelting, casting, aluminum, magnesium and scandium master alloy.
 
Applications of Scandium Aluminum Alloy Al-Sc Alloy:
Scandium aluminum alloys are used in small aerospace industry components. The common scandium content is 2%. The addition of scandium restricts the excessive growth of grains in the heat-affected zone of aluminum welds. Scandium can significantly increase the strength and decrease the grain size. The SC-Al alloy is also used in some sports equipment, including baseball bats, lacrosse sticks, and bicycle frames and related parts.
Aluminum can be made stronger by adding scandium
Scandium aluminum alloy has better welding property
The grain structure remains intact during the forming and extrusion process
When combined with zirconium, it increases with temperature.
Adding a small amount of scandium to the aluminum alloy can promote grain refinement and increase the recrystallization temperature from 250℃ to 280℃. Scandium is a strong grain refiner of aluminum alloy and an effective recrystallization inhibitor. It has a significant effect on the microstructure and properties of the alloy, and greatly improves the strength, hardness, weldability and corrosion resistance of the alloy.
Scandium has a good dispersive strengthening effect on aluminum and maintains a stable non-recrystallized structure under hot working or annealing conditions.
The inhibition effect of scandium on recrystallization can eliminate the recrystallization structure in the heat-affected zone of the weld. The subcrystalline structure of the matrix can be transferred directly to the as-cast structure of the weld seam, which makes the welded joint of an aluminum alloy containing scandium have higher strength and corrosion performance.
The effect of scandium on the corrosion resistance of the aluminum alloy is also related to the refinement of grain and the inhibition of the recrystallization process. The addition of scandium can also make the aluminum alloy have good superplasticity. The elongation of an aluminum alloy containing about 0.5% scandium can reach 1100% after superplastic treatment.
An aluminum alloy containing scandium has become the most competitive high-performance aluminum alloy structure material after Al-Li alloy. The application prospect of scandium aluminum alloy in shipbuilding, aerospace, rocket missile, nuclear energy and other high-tech fields is very broad. By adding a small amount of scandium, a series of new high-performance aluminum alloy materials, such as ultra-high strength and high toughness aluminum alloy and high strength and corrosion-resistant aluminum alloy, can be developed on the basis of the existing aluminum alloy.

Storage Condition of Scandium Aluminum Alloy Al-Sc Alloy :
The damp reunion will affect Al-Sc alloy dispersion performance and using effects, therefore, scandium aluminum alloy should be sealed in vacuum packing and stored in a cool and dry room, the scandium aluminum alloy can not be exposure to air. In addition, the Al-Sc alloy should be avoided under stress.

Application and Prospect of Titanium-Aluminum Carbide Max Phase

/ / no Comments

Products features Research on MAX phases can be traced back as far as the 1960s by Nowotny, et al. It was Nowotny et al. who first introduced the idea of ternary transition metal carbides (or nitrides). Barsoum first referred to the materials as "Mn+1AXn phases" in 2000 (or simply MAX phase). In which M represents the transition metal element and A the primary element. X refers to either C or N.

Titanium-Aluminum Carbide Max phase

In the MAX Phase of the Ti-AL-C, the Al can be quickly diffused and selectively oxygenized. The compact Al2O3 coating will prevent further oxidization. It is possible for the material to self heal at high temperatures due to its microstructure. This property is important to preserve the mechanical properties of the material and increase its reliability. The strength of self-welded Ti3AlC2/Ti2AlC laminates are much better than those of single-phase materials.

Potential of Titanium-Aluminum Carbide Max phase

Aluminum Flakes As Barrier Pigments

/ / no Comments

Aluminum flakes have been used in numerous coating formulations for many years. They are safer than aluminum powders because they have a high surface to weight ratio. In addition, they have been rated as non-hazardous to handle. However, they have not been proven to be effective barrier pigments.

Paints containing aluminum flakes without the inner layer of oxidized aluminum have significantly degraded shear stability. Shear stability can be measured by the difference in lightness values L* before and after shear stress.

An aluminum flake has an inner core of oxidized aluminum that ranges from 5 to 10 nm in thickness. This layer is followed by an alumina support layer that ranges from 50 to 1000 nm. The reflector layer is also a metallic aluminum layer that has a thickness of 10 to 150 nm.

Thin plane-parallel aluminum flakes have improved shear stability and can be used in paints and plastics. Additionally, their mirror-like effects have been enhanced when they are incorporated into coating systems.

Organic encapsulation is commonly employed in the manufacturing of aluminum flakes to provide excellent brightness, dispersion, and outdoor durability. This process also helps to improve handling and application performance. It is especially useful in applications that involve spraying the coating onto a substrate.

Most aluminum flakes are subjected to an encapsulation process to protect the flakes from deterioration. The process can be conducted independently or in combination with silica treatments. Alternatively, additional surface treatment can be selected from chromate or polymer encapsulation with acrylates.
