sintered sic seal ring for Chemical Pump

SIC ceramics not only has good mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, high temperature mechanical properties (strength, creep strength, etc.) is one of the most famous ceramic material. Hot-pressing sintering, pressureless sintering, hot isostatic pressing sintering material, can maintain 1600 ºC high temperature strength, high temperature strength of ceramic materials is one of the best materials. Oxidation resistance is one of the best in all non oxide ceramics. SIC ceramics in petroleum, chemical industry, microelectronics, automobile, aerospace, aviation, paper, laser, mining and industrial applications, such as atomic energy obtained the widespread application.
