High-temperature ceramics, high velocity aircraft nose cones, aviation, aerospace, among other fields are the main uses of hafnium diboride. It could be used in high temperature ceramics, and it is often used in high-temperature high-temperature ovens.

What is Ultra-High-Temperature Ceramics (UHTCs)?
Ceramics at ultra-high temperatures (UHTC). Refractory is a class that has excellent stability at temperatures exceeding 2000°C. They are being investigated as materials for thermal protection (TPS), for coatings that withstand high temperature and for bulk material heating elements.
In the 1960s, the aerospace industry was looking for high-temperature materials. The AIR Force Materials Laboratory began funding the development of a new material to withstand the environment of hypersonic aircraft like the Boeing X-. The fire resistance of binary ceramics was studied in detail. They found that the transition metals borides and carbides had remarkable thermal conductivity, resistance to oxidation, and good mechanical strength. ZrB2 & HfB2 are the most effective composites containing around 20% SiC.
UHTC, broadly speaking, is a boride and carbide, an oxide, nitride or nitride of early-transition metals. Present efforts are focused on heavy early transitional metal borides like zirconium triboride (ZrB2) and hafnium Diboride (HfB2). Other UHTC that are being considered for TPS applications include titanium carbide, titanium nitride and zirconium oxide (ZrN), hafnium triboride (HfN), hafnium dioxide (ThO2) as well as titanium nitride and titanium nitride.
Diborides have a higher thermal conductivity and lower melting points than carbides or nitrides. This gives them excellent thermal shock resistance, making them suitable for high-temperature applications.

The Applications of Hafnium Diboride Powder

admin / 2023-04-09 / no Comments

Overview of Hafnium Diboride Pulver
Hafnium boride This is a gray-colored crystal with metallic luster. It exhibits high conductivity and is stable in chemical properties. It is indistinguishable from all other chemical reagents at room temperature, with the exception of hydrofluoric acids. It can be prepared by heating hafnium oxide or boron carbonide with carbon powder or by reducing hafnium titanate and boron trichloride under hydrogen at 2000. Or by directly reacting hafnium or boron. It is used to make superalloys.
Hafnium Diboride has a high melting point, high hardness and excellent electrical and thermal conductivity. It also exhibits good neutron absorption properties. It can be used to make electrode materials, super-hard materials and neutron absorption substances, as well as ultra-high-temperature materials.
The applications of hafnium dioxide ceramics and composite materials have expanded with the advent of material technology. At home and abroad, it is a major R&D priority to find low-cost, high-quality hafnium dioxide powder. Hafnium Diboride is hard to sinter. To improve the sintering performance it is important to obtain ultrafine powder. While nano-powder offers superior performance, it is costly and difficult to disperse during raw materials processing. The development of submicron hafnium triboride powder has been gaining increasing attention.

Hafnium Diboride HfB2 Powder CAS 12007-23-7

What are the uses for Hafnium Diboride Powder
Hafnium Diboride in wear-resistant coats Because of its exceptional fire resistance, it can also be used in ultra high temperature composite materials (SiC) with silicon carbide. This material is more resistant to oxidation when it has been combined with silicon carbide.
The temperature and pressure determine the resistance to oxidation of hafnium dioxide. A protective oxide scale of hafniumoxide is formed when the temperature is 1500 degrees Celsius and the pressure is 1 atmosphere. HfB2's oxidation resistance will decrease significantly if it is heated above 1600°C or the pressure drops below one atm. These conditions will cause the boiling temperature for B2O3, one of the HfB2 oxidation products, to exceed 1200°C. A protective oxide layer will then form.
Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry vehicle, such as heat shields, for intercontinental ballistic missiles, or aerodynamic fronts. HfB2 forms aerodynamic shapes unlike composite and polymers, and does not ablate during reentry.
Hafnium Diboride has been also investigated as a possibility for new materials in nuclear reactor control rods.
Hafnium-diboride is being investigated as a diffusion barrier for microchips. If the synthesis is correct the barrier thickness could be less than 7 nanometers.

Tantalum Hafnium Coatings

admin / 2023-03-15 / no Comments

Hafnium (pronounced h-fun-ny) is a metallic element with atomic number 72, which belongs to the Group 4 (IVb) of the periodic table. It has a lustrous silvery appearance, and is dispersed to the extent of 3 parts per million in Earth's crust. It is found in minerals of the zirconium group, including altered and native zr-silicates such as alvite and cyrtolite and is also present in commercial sources of rhombohedral and tetragonal zircons.

Among refractory materials, tantalum carbide (TaC) and hafnium carbide (HfC) possess very high melting points which are the highest in the class of inorganic compounds. They are also very resistant to oxidation at oxygen deficient and rich environments.

A new method for forming nanocrystalline TaC and HfC fibers was developed by the ForcespinningTM technique via a nonhalide-based sol-gel process. A systemic study was performed using neat polyacrylonitrile/dimethylformamide (PAN/DMF) to determine an optimal solution viscosity range and the parameters of a spinneret-to-collecting rod distance required for ideal fiber formation.

This synthesis is the first step in a series of large-scale selective synthesis of coatings made of ternary HfTaC systems with predefined stoichiometry and properties, using a unique plasma dynamic experimental setup. The results reveal that this system is a good candidate for the preparation of coatings with a wide range of properties.

Tantalum and hafnium carbides are versatile materials that are often used in aerospace applications. Moreover, they have the potential to provide thermal protection systems for spacecraft that could resist temperatures of nearly 4000degC!

Why Hafnium Carbide Can Form Solid Solution with Many Compounds?

admin / 2023-03-06 / no Comments

What is Hafnium Carbide? Hafnium carbide This gray solid needs to be stored at room temperature. Hafnium carbonide is capable of forming a solid solution when mixed with other compounds such as ZrC or TaC. One example is that of a composite carbide with HfC-4TaC. It has two phases. One is the eutectic form of hafnium carbonide tantalum caride. The other is a needle-like, free graphite phase. You can use it as the throat material for a rocket tube. Hafnium carbide is normally made from hafnium oxide (HfO2), carbon and an inert- or reducing atmosphere. It is heated to 1900 2300. Hafnium carbonide can be combined with several compounds (such ZrC, TaC etc.) to form a solid solution. ).

Introduction to Hafnium
Hafnium is often found in nature alongside zirconium. Zirconium minerals that contain hafnium all include zirconium. Hafnium, zirconium and both are very similar. In stone, beryllium zircon may contain as much as 15% HfO2. Metamorphic zircon can also contain more than 5% HfO2. Both of these minerals do not have much reserves so they are rarely used in industry. Hafnium can be mainly extracted from zirconium. To avoid accidental combustion, sponge hafnium must be carefully removed from the crucible. You should break large pieces of sponge hafnium down into smaller pieces. These can be used to make consumable electrodes and then melt them into ingots. It is important to prevent sponge hafnium from spontaneously combusting during crushing. Further purification of sponge haffnium follows the same procedure as for titanium and zirconium using the iodide-thermal decomposition process. Zirconium has slightly different control conditions. Keep the sponge hafnium blocks in close proximity to the iodization tanks at 600. For comparison, the temperature at the centre of the hot wire is 1600. That is more than 1300 for making a zirconium “crystal rod”. Forging, extrusion and tube drawing are some of the steps involved in molding hafnium.

Hafnium carbide's main uses
It is used primarily to produce control rods for nuclear power plants. Pure hafnium, which is a plastic material, can be processed at high temperatures and resists corrosion. It's an important component of the atomic energy sector. Hafnium, which has a high thermal neutron capture cross section, is an ideal neutron absorber. This can also be used to protect atomic reactors and as a control rod. Hafnium can also be used to propel rockets. The cathode of Xray tubes can be made from it in the electrical sector. Hafnium and other alloys can be used for the protection of frontal layers on rocket nozzles as well as glide reentry airplanes. HfT alloys can also be used in the manufacture of tool steels or resistance materials. Hafnium, an additive element, is used in heat-resistant alloys like tungsten and molybdenum. HfC, due to its high melting point and hardness, can be added to cemented carbides. HfC, the compound having the highest melting points is 4TaC *HfC, has an approximate melting point at 4215.

Why Hafnium disilicide is a refractory intermetallic compound?

admin / 2023-01-29 / 46 Comments

What exactly is hafnium-disilicide? Hafnium disilicide This is a form of transition metal silicide. It is characterized by a high melting temperature, high hardness and wear resistance as well as oxidation resistance. It can be used to make ceramics, as well as various functional and high-temperature resist components. Hafnium diilicide nanomaterials have special optical and electrical properties that could prove useful in optoelectronics.

The preparation of hafnium-disilicide
There are two main ways to dissipate hafnium: the direct synthesis sponge hafnium or the carbon reduction of hafnium oxide, which is the resynthesis metal silicon. Sponge hafnium can be directly synthesized by direct synthesis. It is expensive to produce sponge hafnium, but it is easy to make silicon and hafnium. The mobility of silicon in liquid is poor and it cannot be mixed with silicon. Simple silicon is the most common type of silica. It is possible to synthesize silicon metal by reacting hafnium oxide with carbon. This involves reducing hafnium dioxide with simple carbon in order to make metal hafnium. Only excessive carbon is allowed to reduce hafnium oxide. This will ensure that metal hafnium has no carbon. The silicification and subsequent steps will create silicon carbide impurities. Insufficient carbon will cause a slight amount of hafniumoxide that cannot be reduced. Hafnium oxide will form after silicification. It can cause problems with the product's purity, and it cannot be certified as high purity.

Use of hafnium diilicide
Hafnium silicide is a transition metal silicide. This is a form of refractory intrametallic compound. The unique chemical and physical properties of hafnium disilicide have allowed it to be successfully used in fields such as complementary metal oxide semiconductor devices and film coatings. They also serve to make electric heating elements and photovoltaic material. The preparation requirements for transition metal silicide nanomaterials cannot be met by traditional methods of metallurgy, physical or other methods. For the widespread application of transition silicide nanomaterials, it's important to identify a method that is simple, manageable and easily adaptable.

Price of hafnium Disilicide
Price of hafnium-disilicide products will depend on their purity and size. The purchase volume may also have an effect on its cost. Large quantities of small amounts will result in a lower price. On our official website, you can see the price for hafnium-disilicide.
