Metallurgical Grade Silicon Carbide

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. Its hardness is between fused alumina and synathetic diamond. Mechanical intensity of it is hig-her than fused alumina.it is brittle and sharp and has electrical and heat conductivity in some degree.

Application:

The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.
