Silicon carbide

Silicon carbide is a non-metallic and non-mineral product produced from quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw materials at high temperature above 1800℃ Celsius. Black and green silicon carbides are different types due to different raw materials.

Black silicon carbide is a non-metallic mineral product generated at high temperature above 1800 degrees Celsius with quartz sand (SIO2) and anthracite or petroleum coke (C) as the basic raw materials.

Green silicon carbide is a non-metallic mineral product generated at high temperature above 1800 degrees Celsius with quartz sand (SIO2), petroleum coke (C) and sodium chloride (NACL) as basic raw materials.

Silicon carbide has the characteristics of high hardness, small expansion coefficient, brittleness, and good thermal conductivity. It is widely used in abrasives, grinding of electronic products, refractory materials, special ceramics, coating and plastic modification, grinding wheels production, cutting discs, auto parts, military aviation, etc.

Silicon Carbide Sand

Black silicon carbide sand can be used for: grinding wheel, floor, welding wire, new wear-resistant and corrosion-resistant materials, glass fiber reinforced plastic pipes, oil stone, lettering, sandblasting, casting materials, etc.

Green silicon carbide sand can be used for: grinding wheels, silicon carbide rods, power tools, welding materials, polishing materials, brake pads, glass fiber reinforced plastic pipes, grinding electronic materials, etc.

The production standards for silicon carbide granular sand include: Chinese standards, European standards (FEPA), and Japanese standards (JIS). The international code of black silicon carbide grain sand is: C, and the international code of green silicon carbide grain sand is: GC.
