Black silicon carbide powder,Green silicon carbide powder are inorganic non-metallic materials with silicon carbide (SiC) as the main component.

Black silicon carbide powder contains about 95% SiC and is black because it contains a small amount of impurities. It has high hardness, with a Mohs hardness of 9.2-9.5, good wear resistance, corrosion resistance and high temperature resistance, and good thermal conductivity.
Application of black silicon carbide powder: It is often used in the abrasive industry to make grinding tools such as grinding wheels, sandpaper, and grinding pastes, and is used for grinding metal materials such as cast iron, copper, and aluminum, as well as non-metallic materials such as ceramics and stone. In the field of refractory materials, it can be used as an additive to improve the strength, wear resistance, and thermal shock resistance of refractory materials, and is used for the lining of high-temperature equipment such as steelmaking furnaces and glass kilns. It can also be used to manufacture sandblasting nozzles to remove rust, paint, and roughen metal surfaces.

The SiC content of green silicon carbide powder is generally above 97%, with high purity and green color. Its hardness is slightly higher than that of black silicon carbide, with a Mohs hardness of about 9.5 - 9.7. It has higher wear resistance and better cutting performance, and its thermal conductivity and electrical conductivity are also excellent.
Application of green silicon carbide powder: Mainly used for precision grinding and polishing, such as processing of high-precision products such as optical lenses, semiconductor wafers, and ceramic cutting tools, to obtain better surface finish and precision. In the electronics industry, it can be used as abrasive materials for manufacturing semiconductor epitaxial wafers, and as a filler for electronic packaging materials to improve the thermal conductivity of packaging materials. It can also be used to manufacture advanced refractory materials and special ceramics, such as silicon nitride combined with silicon carbide ceramics, for high-temperature, wear-resistant, and corrosion-resistant industrial environments.
