Black Silicon Carbide

Black silicon carbide is produced during high temperatures in an electrical resistance type furnace, with quartz sand and petroleum coke as its main raw materials.  Its hardness is between fused alumina and synthetic diamond.  The mechanical intensity of this is higher than fused alumina.  It is brittle and sharp and has electrical and heat conductivity to some degree.  The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, and rubber, etc.  It is broadly used as a refractory material and metallurgical additive.
