s. 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.
