Is Silicon Carbide a Good Conductor of Electricity
Silicon carbide is an extremely hard bluish-black insoluble crystalline substanceproduced by heating carbon with sand at a high temperature andused as an abrasive and refractory material. There are many appliions of silicon carbide, such as slide bearings, sealing rings, wear parts, sintering aids, crucibles, semiconductor appliions, heating elements, burner nozzles, heat exchangers.
