Silicon carbide ceramic ball

SiC ceramics not only have excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance, etc.) are the best known ceramic materials. Hot pressing sintering, non-pressing sintering, hot isostatic pressing sintering materials, its high temperature strength can be maintained to 1600℃, is the best high temperature strength of ceramic materials. The oxidation resistance is also the best of all non-oxide ceramics. Another name for emery.
