As a white pigment filler of high quality, has a variety of uses. It can be used in plastic profiles, colormasterbatch, paints (emulsion, powder, and sand), paper making, chemical fibre, cosmetics etc. It can be used with both the water-based system, the solvent system, and the solvent free system. The different application and application systems have additional requirements in selecting organic coatings agents. Traditional TMP and peg are no longer sufficient to meet these requirements. They also have some negative effects such as the problem of bubbles. Depending on the different USES for titanium dioxide, different organic treating agents are needed to treat titanium dioxide in order to achieve satisfactory treatment effects. In addition to the different USES for titanium dioxide, there are also differences in titanium dioxide application performance requirements.
Plastics - Requirements on titanium dioxide
1. High viscosity extrusion/dispersion lubricant
As plastic products become stronger and cheaper, they add more color filler. However, as the resin proportion decreases and compatibility between components becomes more challenging, it can cause the surface to be rough and uneven in color. Consider the colormasterbatch that is commonly used in plastic industry: it is usually made by extrusion of titanium dioxide and granulation after being kneaded with high temperature organic resins such as polyethylene wax or high-pressure polyester. It is necessary to use the least amount of carrier resin to moisten as many titanium dioxide particles as possible in order to achieve a high-concentration white masterbatch. This will avoid low resin compatibility when applied. In order to produce masterbatches, titanium dioxide must have excellent surface wetting and lubrication characteristics. If not, it is difficult to granulate or disperse.

2. Temperature/weather Resistance
Before processing or forming, the vast majority of plastics products, regardless of their type, processing method, and resin used, must be in high-temperature melt with titanium dioxide and additives. Processing temperatures for plastics are around 200 degrees, or higher. The decomposition of some components at this temperature will cause pigment migration, porosity and a serious impact on the physical strength and surface quality of plastic products. Each component of the formula should have excellent temperature resistance. Besides, the UV resistance of most plastic products, such as plastic films, electrical appliances, used outdoors or in a healthy light environment must be taken into consideration. During the production of PVC plastics, lead stabilizers are usually added. This type of stabiliser is easily reacted with other active chemical substances at high temperature and produces black substances. Lead stabilizers cannot react with organic coating agents on titanium dioxide surfaces.

3. Dry powder fluidity/moisture resistant
As more factories adopt continuous production lines in the plastic industry, raw materials related to these products (such a resins, fillers and pigments) are also metering continuously using transmission belts or vibratory leakage sieves. Imagine that the flow rate of titanium dioxide dry is low. The powder will then get stuck in the belt of the transmission or block the screen hole. This can lead to titanium dioxide not being accurately measured and added smoothly.

Introduction to silicon carbide products
Silicon carburide also known by the names moissanite, emery or coal coke, is a substance inorganic with a formula SiC. It is produced by a high-temperature resistive furnace using raw materials, such as wood chips, quartz sand or coal coke. (Salt is required to make green silicon carbide). In nature, silicon carbide is found in the rare mineral moissanite. It is the most popular and cost-effective refractory material among the non-oxide materials like C, N, and B. It can also be called refractory or gold steel. In China, silicon carbide is made up of two types: green and black. They are both hexagonal crystals and have a specific gravity ranging between 3.20 and 3.25% and a microhardness range of 2840-3320kg/mm2.

Both black silicon carburide and green silica carbide belong to the aSiC. Black silicon carbide has a SiC content of 95% and is more durable than green silicon carbide. It is used to process materials that have low tensile resistance, like glass, ceramics or stone. Green silicon carbide has a SiC content of over 97% and is self-sharpening. It is used primarily for the processing of cemented carbide (a titanium alloy), optical glass and titanium alloy. Also, it can be used for honing and fine grinding tools made from high-speed steel and for cylinder liners. There is also a cubic silicon-carbide, which is yellow-green crystals prepared through a special method. The abrasive tools used to make them are suitable for superfinishing bearings. Surface roughness is processed between Ra320.16microns and Ra0.040.02 microns.

Aside from being an abrasive, silicon carbide can be used in many other ways. This is due to its chemical stability, high thermal conductivity (low thermal expansion coefficient), and wear resistance. The powder of silicon carbide can be used to coat a specific impeller, cylinder or other part of a turbine. The inner wall of the refractory can be improved to increase its resistance to abrasion and its life span by upto 2 times. Low-grade Silicon carbide (which contains about 85% SiC), which is a deoxidizer of excellent quality, can improve the steelmaking process and speed. It also allows for better control over chemical composition. Silicon carbide can also be used to produce silicon carbide for electric heater elements.
It is the second hardest substance in the world, after diamonds (10). It has excellent heat conductivity and is a semi-conductor.

There are at least 70 crystal forms of silicon carbide. Allomorphs of silicon carbide are the most common. It has a hexagonal crystalline structure and is formed above 2000 degC at high temperatures. Below 2000 degC b Silicon Carbide with cubic crystals, similar to a diamond, is produced. The network can be seen on the page. It is not only eye-catching, but also more stable than the a type. A type of silicon carbide called m-silicon carbide is more stable and makes a nicer sound when it collides. However, until now these two types had not been used commercially.
Due to its high sublimation temp (approximately 27°C) and 3.2g/cm3 specific weight, silicon carbide makes a great raw material for high temperature furnaces or bearings. It does not melt at any pressure, and it has a very low chemical activity. Its high thermal conductivity and breakdown electric field strength as well as its high maximum current densities have led many to try and use it in place of silicon for high-power semiconductor components. It has a high coupling effect to microwave radiation.
The colorless silicon carbide produced in industrial production is caused by iron impurities. The silica coating on the surface of the crystal gives it a rainbow-like appearance. To

Pure silicon carbide is a transparent, colorless crystal. The impurities in industrial silicon carbide cause it to be light yellow or green. It can also be blue, black, or dark brown. Its clarity varies according to its purity. The cubic b-SiC is also known as cubic silicon carburide. The different stacking of silicon and carbon atoms creates a variety of a SiC variants. Over 70 types have been identified. Above 2100degC bSiC turns into aSiC. Industrial silicon carbide is produced by refining petroleum coke and high-quality sand in a resistance oven. The silicon carbide blocks that have been refined are crushed and then subjected to acid-base washing, magnetic separation, sieving, or water selection.
It is artificial because silicon carbide has a low natural content. The standard method is a mixture of quartz sand, coke, silica and oil coke. Add salt and wood chips and heat to 2000degC in an electrical furnace.
Its excellent hardness has made it an indispensable abrasive, but its range of applications goes beyond that of general abrasives. Due to its thermal conductivity and high-temperature resistance, it is a popular choice for kiln furniture in tunnel kilns. The electrical conductivity of this material makes it a vital electric heating element. SiC is made by melting SiC blocks, or pellets. Because they are hard and contain C, SiC pellets used to be called emery. It is not natural emery, also known as garnet. Quartz, petroleum coal, etc. are usually used to produce SiC smelting slabs in industrial production. As raw materials, as auxiliary recovery material, or as spent materials. After grinding or other processes, the materials are blended to a charge that has a reasonable particle size and ratio to adjust its gas permeability. An appropriate amount must be added. To prepare green silicon carbide at high temperatures, you need to add the correct amount of sodium chloride. Special silicon carbide electric heaters are used for the thermal equipment to prepare SiC smelting at high temperature. Its main components are the furnace bottom with electrodes in the interior, the sidewall that can be removed, and the furnace core. Both ends are electrode-connected. Known as buried-powder firing, this method of firing is used in an electric furnace. As soon as you turn it on, the heating begins. The furnace core is at 2500degC (or even higher, between 2660-2700degC). SiC synthesizes at 1450degC (although SiC primarily forms above 1800degC), and co is released. SiC decomposes when the temperature is >=2600. The decomposed si, however, will form SiC and C in the charged.
Each electric heater is equipped with transformers. Even so, during production only one electric heater is operated to maintain a constant voltage by adjusting the voltage based on the electrical load characteristics. It takes about 24 hours to heat up the high-power furnace. The reaction that generates SiC stops after an interruption in power. After a cooling time, the sidewalls can be removed. The charge is then gradually removed. Silicon carbide can be divided up into many different categories. These are further divided according to their use environment and more often than not, silicon carbide is used in machinery. Silicon carbide seal rings can, for example, be used to seal mechanical seals. These seal rings can be further divided into static ring (used on mechanical seals), moving ring (used on mechanical seals), flat ring (used on flat surfaces) and more. Our silicon carbide products can be made in different shapes according to the customer's requirements. For example, we can produce silicon carbide plates and rings.
One of the silicon-carbide products is silicon carbide, which has high hardness, corrosion resistance and high temperature strength. Silicon carbide ceramics have a wide range of applications.
Silicon carbide ceramics are ideal for seal rings. They have a high level of chemical resistance and wear resistance. The friction coefficient of silicon carbide ceramic is lower when combined with graphite than cemented carbide and alumina. Therefore, it is suitable for PV values that are high, particularly in conditions where strong acids or alkalis will be transported. Our SIC-1 silicon carbid atmospheric sintered product range has high density and high hardness. It also comes in large batches with the capability to produce products of complex shapes. They are resistant to strong acids and Alkalis and have exceptionally high PV values. The SIC-3 materials produced by our company contain graphite. When combined with other materials, the friction coefficient of silicon carbide is low because it contains fine dispersed graphite particles. It is self-lubricating and therefore ideal for air-tight, dry-friction sealing. It is used to increase the seals' service life, and improve the reliability of the work.

After high-temperature calibration, furnace charges are unreacted materials (to preserve heat in the furnace), silica carbide oxycarbide material (semi reactive material, main components C and SiO), amorphous material layer (the main component is 70% to 90% SiC; it's Cubic SiC that is b-sic. C, C-SiO2, 40% to 60% of the material is made up of carbonates Fe Al Ca Mg), second grade material layer ( The binder layer is used to bond the very tight material. It is composed of C, SiO2, Fe, Al Ca Mg Carbonate, 60% to 70% SiC. The unreacted and a fraction of the oxycarbide layers are typically collected as spent materials. A portion of this oxycarbide is also collected along with the amorphous and second-grade products, as well as a portion from the bonded layer, as recycled material. Large lumps and impurities, as well as some charges and tight bonds are discarded. The first-grade material is classified, then coarsely or finely crushed. It's treated chemically, dried, sieved, then magnetically separated. It is necessary to go through the water selection process in order to produce silicon carbide.

The difference between graphite and graphene |
Graphene is just an atomic layer of graphite-a layer of sp2-bonded carbon atoms arranged in a hexagonal or honeycomb lattice. Graphite is a common mineral composed of multiple layers of graphene. The structural composition of graphene and graphite and their manufacturing methods are slightly different. This article focuses on the difference between these two materials.

Graphite mineral
Graphite is one of the three naturally occurring allotropes of carbon. It naturally occurs in metamorphic rocks in different parts of the world, including some parts of South America, Asia and North America. This mineral is formed due to the reduction of deposited carbon compounds during metamorphism.
Graphene
The chemical bonds in graphite are similar to those in diamond. However, the lattice structure of carbon atoms contributes to the difference in hardness of these two compounds; graphite contains two-dimensional lattice bonds, while diamond contains three-dimensional lattice bonds. The carbon atoms in each layer of graphite contain weaker intermolecular bonds. This allows the layers to slide against each other, making graphite a soft and ductile material.
Various studies have proved that graphite is an excellent mineral with several unique properties. It conducts heat and electricity, and maintains the highest natural strength and rigidity even at temperatures exceeding 3600degC. This material is self-lubricating and also resistant to chemicals.
Although there are different forms of carbon, graphite is very stable under standard conditions. According to its form, graphite is widely used in various applications.
Graphite has unique properties that exceed graphite. Although graphite is often used for reinforcement of steel bars, it cannot be used alone as a structural material due to its thin plane. On the contrary, graphene is the strongest material ever; it is more than 40 times stronger than diamond and more than 300 times stronger than A36 structural steel.
Because graphite has a planar structure, its electronic, acoustic and thermal properties are highly anisotropic. This means that phonons are easier to pass through an airplane than when passing through an airplane. However, graphene has a very high electron mobility, and like graphite, since there are free p(p) electrons in each carbon atom, it is a good electrical conductor.

However, graphene has a much higher electrical conductivity than graphite, which is due to the appearance of quasi-particles, which are electrons, which function as if they have no mass and can travel long distances without scattering. In order to fully achieve this high conductivity, doping is required to overcome the zero density of the state that can be visualized at the Dirac point of graphene.
Graphene production or separation
Scientists use many techniques to produce graphene. Mechanical peeling, also known as tape technology, is one of the effective ways to create single-layer and few-layer graphene. However, various research institutions around the world are trying to find the most effective way to efficiently create high-quality graphene on a large scale.

Chemical vapor deposition (CVD) is the most suitable technology for producing single-layer or several-layer graphene. This technology can extract carbon atoms from carbon-rich sources through reduction. However, the main disadvantage of this technology is that it is difficult to locate a suitable substrate to grow the graphene layer, and it is difficult to remove the graphene layer from the substrate without changing or destroying the atomic structure of the graphene.

in conclusion
Other techniques used for graphene growth are ultrasonic treatment, thermal engineering, carbon dioxide reduction, cut open carbon nanotubes and reduction of graphite oxide. The latter technique, which uses heat to reduce graphite oxide to graphene, has recently attracted great attention due to reduced production costs. Nevertheless, the quality of the graphene currently produced cannot meet the theoretical potential of the material, and more time is needed to complete it.

Scientists have developed a highly selective conversion of carbon dioxide
Carbon dioxide conversion technology is a way to reduce the amount of carbon dioxide in our atmosphere and obtain a variety of high-value-added fuels. Electrocatalytic Carbon Dioxide Reduction Technology has many advantages, including the ability to operate at normal pressure and temperature, the ability to create an artificial closed cycle of carbon, etc. This technology offers a promising solution for current renewable energy utilization and chemical fuel synthesis. It is difficult to implement the carbon dioxide electroreduction technique in industry due to the difficulty of realizing the application. This is because the technology requires a rational design, controllable synthesis, and an understanding of the catalytic mechanisms.
The researchers suggested that the "near neighbour effect" of a nano-needle's tip would promote the electro-reduction of CO2. The structure of the cadmium sulfur nano-needle-array was developed through high-throughput screening in the intelligent micro-wave reactor. The study concluded that as the distances between the needle tips decreased, the potassium enrichment would continue to grow. Due to the "near neighbour enrichment effect", the performance of this multi nano-tip cadmium catalyst is superior to other transition metal chalcogenide catalysts.

What is Magnesium Nitride? Magnesium-nitride This inorganic substance is composed of magnesium and nitrogen. It has a molecular formula Mg3N2 with a weight of 100.9494. Belongs in the cubic crystal system. At room temperature, pure magnesium nitride powder is yellow-green. However, magnesium nitride that contains some magnesium oxide is off-white. Ammonia is formed when magnesium nitride reacts to water, as it does with many metal nitrides. Magnesium strips can be heated in nitrogen and then burned to produce magnesium nitride. It is often used as a catalyst.
Magnesium nitride chemical and physical properties
Magnesium (Mg3N2) nitride is an inorganic compound with a cubic crystal structure composed of nitrogen. At room temperature, pure magnesium nitride powder is yellow-green. However magnesium nitride that contains some magnesium oxide impurities appears off-white. It is soluble in acid and slightly soluble with ethanol, but not ether.
Magnesium Nitride, like other metal nitrides that react with water, forms ammonia. Ammonium salts and non-metal oxides are produced when magnesium nitride is reacted with acid or water containing nonmetal oxides.

Magnesium nitride preparation
To prepare magnesium nitride The strip of magnesium can be burnt with nitrogen. The reaction is:
It is possible to produce magnesium oxide in the reaction above if the nitrogen used is not pure. The reaction is better in dry NH3 gases.
Install the magnesium chips in a sintered or porcelain boat. Install the boat in a tube made of porcelain. The porcelain tube has a T-shaped tube attached at one end. The porcelain tube ends are connected with U-shaped tubes, which are filled with desiccant. The absorption device is made up of two conical flasks that are filled with dilute acid. Avoid inserting the tube of first absorption bottle beneath the surface of dilute sulfuric.
Pour dry NH3 or N2 into porcelain tube. When the second bottle of absorption stops bubbling it means that air is out of the tube. The temperature will be increased to 800-850degC. The magnesium powder will then be heated for 4hrs. As the magnesium powder heats up, the reaction begins. H2 must also be produced. The pressure of the NH3 during the reaction should be greater than that outside atmospheric pressure in order to avoid back-suction. After the reaction has finished, shut off NH3, but keep the temperature at the same level. Continue to pass N2 over 1.5h in order to remove the adsorbed NH3*Mg3N2. The NH3*Mg3N2 molecule is highly liquescent, and should be stored in an airtight container.
When the magnesium belt is burnt in the atmosphere, magnesium oxide and magnesium nitride are produced.
Magnesium Nitride Application
1. Use as a catalyst in the preparation of nitrides containing other elements that have high hardness, thermal conductivity and corrosion resistance. Also used for high temperature resistance. Magnesium nitride acted as a catalyst when cubic boron-nitride, a new material, was synthesized successfully for the first time.
2. Additives in the production of high-strength alloy steel. Magnesium (Mg3N2) can replace desulfurized magnesium in construction steel smelting, improving the density, strength, durability, and tensile strength of steel. Magnesium nitride can be used to desulfurize construction steel, and it is also a cost-effective way to do so.
3. Preparation special ceramic materials
4. Foaming Agent for Manufacturing Special Alloys
5. Special glass is used to manufacture;
6. Catalytic Polymer Crosslinking
7. Recycling of nuclear waste
8. Use as a catalyst material in the synthesis for diamond synthesis, and cubic boron-nitride.
