Products Description
Black silicon carbide powder is generally made by mixing a higher proportion of graphite and a lower proportion of silicon powder, and then undergoing multiple processes such as roasting and carbonization. Another common preparation method is to use quartz sand, petroleum coke, silica, etc. as the main raw materials and smelt them at high temperature in a resistance furnace. The main raw materials include quartz sand, petroleum coke, silica, etc. The quality and purity of these raw materials have an important impact on the performance of the final product.
Black silicon carbide powder has the characteristics of high hardness, high strength, high density, etc. Its hardness is close to that of diamond. At the same time, it also has good thermal conductivity and low thermal expansion coefficient. Black silicon carbide powder is chemically stable at room temperature and is not easy to react with acids and alkalis. However, at high temperatures, it can react with certain oxides to generate corresponding silicates or carbides.
Black silicon carbide powder is widely used in many fields due to its excellent physical and chemical properties. Black silicon carbide powder has extremely high hardness, second only to diamond, so it is very suitable for making high-precision grinding tools. These grinding tools are widely used in the processing and polishing of hard and brittle materials such as cast quartz glass and diamond, and can achieve efficient and precise grinding and polishing effects. Black silicon carbide powder has excellent stability and corrosion resistance at high temperatures, so it is widely used in the manufacture of refractory materials and high-temperature seals. These refractory materials can withstand various harsh conditions in high-temperature environments and ensure the stable operation of equipment and processes. In the electronics industry, black silicon carbide powder is used as a manufacturing material for electronic components such as semiconductors due to its good conductivity and thermal stability.
In addition, it can also be used to manufacture electric heating elements, high-temperature semi-superconductor materials, far-infrared boards, and lightning arrester valve plate materials, etc., providing important support for the development of the electronics industry. In addition to the above major application areas, black silicon carbide powder is also used to manufacture high-performance materials such as ceramic bodies and bulletproof materials. In ceramic manufacturing, it can improve the strength and wear resistance of ceramics; in the manufacture of bulletproof materials, it can serve as a reinforcing phase to improve the impact resistance of the material.
