Is Silicon Carbide a Good Conductor of Electricity

Silicon carbide is an extremely hard bluish-black insoluble crystalline substance produced 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.

Silicon carbide - excellent for high temperature …

30/3/2021· Another interesting feature of silicon carbides is their relatively high thermal conductivity. Here again, the CVD material excels by achieving at least 150 W/mK, which exceeds that of common steels and cast iron. Thermal conductivity does decrease with temperature and must be considered carefully against specific appliions.
