Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze, aluminum, stone, leather, rubber, etc.

1. Grinding non-ferrous materials, rock, stone, and leather, rubber, finishing tough and hard materials.
2. Bonded Abrasive tools, lapping and polishing.
3. Widely used as a metallurgical additive and refractory material.

Green silicon carbide is produced as the same type as the black silicon carbide, except the different raw materials. Its crystallization has higher purity and hardness. Green silicon carbide is suitable for processing hard alloy, metallic and non-metallic materials with hard and brittle feature such as copper, brass, aluminum, magnesium, jewel, optical glass, ceramics etc. Super micropower of it is also a kind of ceramics material.
1. It is suitable for grinding high-speed, high carbon steel
2. High-grade refractory materials
3. Abrasives tool
4. Grinding and polishing
5. Ceramics
6. LED
7. Sandblasting
8. Aviation
9. wire-electrode cutting
10. Photovoltaic and solar energy
