[Detailed introduction]
Silicon carbide (also known as: moissanite, emery or refractory sand), chemical short form: SiC, is with quartz sand and petroleum coke (or coal), wood chips as raw material through high temperature resistance furnace smelting and a refractory material. Silicon carbide in nature also exist in rare minerals, Mo Sangshi in. In the modern C, N, B, and other non oxide high - tech refractory raw materials, silicon carbide is the most widely used, the most economical one. China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two kinds, are six square crystal, the proportion is 3.25 ~ 2840, the micro hardness is 3.20 ~ 3320kg/mm2.
