black carborundum grit black silicon carbide sicheng

Black silicon carbide powder. Black Rainbow Carborundum is produced in electrical internal resistance furnaces from high purity silica sand and petroleum coke. This product has high hardness, abrasion resistance, thermal shock resistance, and strength at high-temperature ranges. It can be used in refractory and grinding media. Carborundum Grit, with the chemical symbol SiC, is a solid industrial mineral crystalline. It is used as an abrasive, semiconductor, and ceramic, commonly referred to as carborundum. SiC exists naturally in a scarce mineral called moissanite. When impurities are added, silicon carbide crystals appear green or black, depending on the contaminant level.
