Silicon carbide is a non-metallic mineral product produced at high temperatures above 1800 degrees Celsius with quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw materials.It has the characteristics of high hardness, small expansion coefficient, brittleness, good thermal conductivity, etc., widely used in abrasive abrasives, electronic products grinding, refractory materials, special ceramics, foam ceramics, coating plastic addition modification, auto parts, military aviation, steel deoxidizer. The company mainly produces various content specifications of black silicon carbide.
