Black Silicon Carbide Powder Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand, petroleum coke and bits of wood as its main raw materials. Its hardness is between fused alumina and diamond. Mechanical intensity of it is higher than fused alumina. It is crisp,sharp and have certain degree
