Prodcut Name:Silicon Carbide Black

Product Description

Black silicon carbide is produced from quarts sand and coke or coal as its main raw material, 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.
