Black silicon carbide
Silicon carbide sand and powder for deoxidization of steelmaking in specification of 50, 60, 70, 80 and 90 can be customized.
Black silicon carbide is a nonmetallic mineral product formed with quartz sand (SIO2), anthracite or petroleum coke (C) as raw materials at a high temperature of 1800 Celsius or above, featured by high hardness, small coefficient of expansion, brittle property and good thermal conductivity, widely used as a deoxidant in abrasives, grinding of electronics, refractory, special ceramics, foam ceramics, modification of coating and plastics, auto parts, war industry and aviation, steelmaking, etc.
Black silicon carbide is classified into black silicon carbide sand and black silicon carbide powder.
Applications: Silicon carbide has broad applications, such as solar and semiconductor wafer wire sawing; crystal and ferrite polishing; ceramic and special steel precision polishing; bonded and coated abrasive tools; cutting and polishing; non-ferrous metal lapping such as glass, stone, agate and high-grade jewelry; high-grade refractory materials , engineering ceramic, heating elements and thermal elements.
