Black silicon carbide is a non-metallic mineral product produced from quartz sand (SiO2) and anthracite or petroleum coke (C) as basic raw materials at high temperatures above 1800 degrees Celsius. It has high hardness, a low thermal expansion coefficient, brittleness, and good thermal conductivity.

 

It is made after crushing, impurity removal, pickling, washing, drying and screening; it has high cleanliness, high purity, high content, good particle shape and excellent sharpness, and is widely used in abrasives, electronics Product grinding, refractory materials, special ceramics, foam ceramics, addition and modification of coating plastics, auto parts, military aviation, deoxidizers for steelmaking, etc.
