Polishing Abrasive Silicon Carbide

Silicon carbide exists in rare minerals in nature, moissanite. Silicon carbide is also called carbon silicon stone. Among contemporary non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one.

Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, and salt is added as an additive, and is smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum.
