Silicon Carbide | GNPGraystar Specialty Materials

Silicon Carbide occurs in nature only as the extremely rare mineral moissanite. Synthetic Silicon Carbide has been mass-produced since 1893 for use as an abrasive. Silicon Carbide (SiC) is produced at a high temperature in an electrical resistance arc furnace with quartz (silica) and petroleum coke (carbon) as its primary raw materials. The final product is sharp and friable with outstanding
