Silicon Carbide

Black silicon carbide is produced from quarts sand and coke or coal as its main raw marterial, melted at high temperature in an electric arc furnace. Its hardness is between fused alumina and synthetic diamond, while mechanical intensity is higher than fused alumina. It is brittle and sharp. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also widely used as refractory material and Metallurgical additive.
Green silicon Carbide is produced in the same way of Black silicon Carbide except some difference in raw material. 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.
