Black Silicon Carbide Micropowder (Black Silicon Carbide Micropowder) is a kind of micron-sized powder material made of silicon (Si) and carbon (C) reacted at high temperature, with the color of dark grey to black, high hardness, abrasion-resistant, high thermal conductivity, which has a wide range of applications in the fields of abrasive, refractory, electronics, photovoltaic, and so on.
black silicon carbide powder main features
1. High hardness
The hardness of black silicon carbide micropowder is close to diamond, with a Mohs hardness of about 9.2, making it an ideal super-hard abrasive. It is commonly used in the manufacture of various abrasives and polishing materials, and is suitable for processing high hardness materials such as ceramics, glass, gemstones, and cemented carbide.
2. Good abrasion resistance
Black silicon carbide micropowder has excellent abrasion resistance and is especially suitable for use in high abrasion environments. It is widely used in products such as grinding and polishing, coating materials and grinding wheels to improve the wear resistance and service life of materials.
3. Excellent Thermal Conductivity
Due to the high thermal conductivity of black silicon carbide, it maintains good thermal conductivity in high-temperature environments. It is commonly used in electronic devices and high-temperature equipment that require heat dissipation materials, such as thermal conductive heat sinks, ceramic substrates and thermoelectric materials.
4. High Temperature Resistance and Oxidation Resistance
Black silicon carbide micropowder shows excellent stability at high temperatures, with a melting point as high as 2700°C, and also has strong oxidation resistance. It is often used in the lining of high-temperature furnaces, refractory materials, and in furnace tubes and kilns in the smelting industry.
5. Chemical Stability
Black silicon carbide micropowder shows high chemical stability in both acid and alkali, and is able to keep its properties stable in the harsher chemical environments. Therefore, it can also be used in equipment and containers that handle corrosive substances.
6. Photovoltaic and electronic applications
In the field of photovoltaics, black silicon carbide micropowder can be used in the production of cutting tools for polysilicon wafers, as well as in the polishing process of photovoltaic products. In the field of electronics, black silicon carbide micropowder is also used as a material for high-frequency and high-temperature devices and high-power switching components due to its semiconductor properties.
black silicon carbide powder main applications
- Abrasives: Manufacture of high hardness abrasives such as grinding wheels, cutting blades and polishing powders;
