Silicon Carbide By Gongyi Qingyun Refractories Co., Ltd.

Owing to our years of industry experience and market understanding, we are leading Manufacturer and Supplier of Silicon Carbide in Gongyi, Henan, China. Green silicon carbide mainly divides into the black silicon carbide and silicon carbide.Silicon carbide is also called the moissanite.In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic.Can be called corundum sand or refractory.Among them: black silicon carbide is quartz sand and petroleum coke and high quality silica as the main raw material, through high temperature electric resistance furnace smelting.Its hardness is between fused alumina and between diamond and mechanical strength higher than that of corundum, sharp and crisp.Black silicon carbide, metal luster, containing SiC by more than 95%, the strength is larger than the green silicon carbide, but hardness is low, it is mainly used for grinding of cast iron and non-metallic materials.
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting.There is also a rare mineral silicon carbide in nature, and the mo SangShi.Silicon carbide is also called the moissanite.In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic.
