Silicon carbide is also called moissanite. Among contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is a widely used and economical one, which can be called gold steel sand or refractory sand. At present, China's industrially produced silicon carbide is divided into two types: black silicon carbide and green silicon carbide.
Black silicon carbide contains about 95% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used for processing materials with low tensile http://www.zhongxing-silicon.com/silicon-carbide/
