Black silicon carbide FOR ABRASIVE (HENAN JUNSHENG REFRACTORIES LIMITED)is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc Black silicon carbide is also broadly used as refractory material and metallurgical additive.
