Black silicon carbide (BLACK SILICON CARBIDE C) in the non-metallic mineral quartz sand (SiO2) and anthracite or petroleum coke (C) more than 1800 degrees Celsius as the basic raw material in high temperature conditions smelted. Its products are of high hardness between corundum and diamond, mechanical strength higher than corundum, brittle and sharp expansion coefficient is small, fragile, has good electric conductivity. Black silicon carbide in black silicon carbide particle size sand and black silicon carbide powder two categories, black silicon carbide products are widely used in the production consolidation coated abrasive, grinding of electronic products, refractory materials, special ceramics, ceramic foam, etc., and also used paint plastic additives, automotive accessories, military aviation; black silicon carbide grinding wheel suitable for grinding metal and non-metallic materials to resist the tensile strength, such as gray cast iron, brass, aluminum, stone, leather and rubber. In addition, black silicon carbide can be used for the production of refractory products and electronic products, etc.; low-grade silicon carbide (SiC-containing approximately 85%) is excellent in a deoxidizer, it can accelerate the steelmaking speed, and to facilitate the control of chemical composition, improve the steel quality. I produced F8 - F200 mesh, JIS240 thin black silicon carbide, a black silicon carbide (98.5%), two black silicon carbide (90%), high quality and low price, large supply, please contact us!
