Black Silicon Carbide Grain/SIC Black silicon carbide is produced from quartz sand and high quality anthracite/petroleum coke under high temperature in and electric resistance furnace. It looks black and has a microhardness of 2800-3300kg/mm2. Abrasive tools made of it, are fit to grind metals and non-metals materials of low tensile strength, for example, grey cast iron, brass, alumina, stone, leather and hard rubber etc. It can also be used for refractory purpose or in electronic industry. Usage: (1) As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand tiles etc. (2) As the metallurgical deoxidizer and high temperature material. Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials. (3) High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers. (4) Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high temperature resistant to oxidation. The physical and chemical analysis:
