The hard material of mechanical seal silicon carbide ceramics:

Silicon carbide ceramic is a new type of friction pair material with excellent performance. It is light in weight, high in specific strength, and strong in anti-shooting ability; it has a certain degree of self-lubrication, low friction coefficient; high hardness, wear resistance, good matching performance; chemical stability, corrosion resistance; good thermal conductivity, heat Shock. According to different manufacturing processes, silicon carbide mainly includes hot pressing sintered SiC, atmospheric sintered SiC, and reaction sintered SiC. Table 5-9 respectively lists the performance, characteristics and applicable occasions of the three types of silicon carbide. Sand mill mechanical seal
