Profile: Shenzhen Fuyongwei Imp & Exp Co., Ltd. specializes in offering silicone carbide series products. Black silicon carbide is produced at high temperature in an electric resistance furnace, with quartz sand and petroleum coke as its main raw material. Its mechanical intensity is higher than fused alumina. It is brittle, sharp, and has electrical heat conductivity. It is widely used as refractory material and metallurgical additive. Green silicon carbide is produced in the resistance type electric furnace with petroleum coke, quartz sand salt, and other material as its raw materials. It has high intensity even at high temperature. Green silicon carbide is a kind of man-made material with a good thermal conductivity.
