High-purity Silicon carbide micro powder is the basic raw material of normal pressure sintered silicon carbide industrial ceramics. Its particle size D50 is 0.5 microns, with high purity, small particle size, large specific surface area, high surface activity, and purity greater than 98.5%. It is suitable for the production of various mechanical seal rings, bearings, bushings and other friction materials. Widely used in petrochemical, electric power, light industry, aerospace, automobile, papermaking and sewage treatment and other industrial fields. And when the normal pressure sintered Silicon carbide micro powder is used together with carbon graphite, the friction coefficient will be minimized, and it can be used as a high-parameter mechanical seal
