. Silicon Carbide - an overview | ScienceDirect Topics 0000. Silicon-carbide is commercially produced from silica sand (quartz) powder and petroleum coke (CPC)/anthracite coal in required proportion in an electric furnace. Heat at the core of such furnace reaches as high as 0000 °C. A yield of 00.0 ton black silicon carbide is obtained from a furnace charge of 00 ton by this process. Silicon Carbide - an overview | ScienceDirect Topics Among four types of carbide formed by metals with carbon (e.g. salt like carbides, metallic carbide, and diamond like carbides) silicon carbide falls in the diamond like carbide egory. Silicon-carbide because of its inherent hardness, high thermal conductivity and semiconductor behavior finds nuer of important industrial appliions.
