الوصف

Black silicon carbide is produced from quartz sand and high quality anthracite/petroleum coke under high temperature in and electric resistance furnace. Black silicon carbide looks black and has a microhardness of ********0kg/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. Black silicon carbide can also be used for refractory purpose or in electronic industry.
