        Why is silicon carbide ceramic materials?

        2019-01-03 22:49

        Why is silicon carbide ceramic ceramic materials in the high temperature strength good material? Below small make up to introduce as follows:
        Silicon carbide ceramics not only has excellent mechanical properties at room temperature, high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, and high temperature mechanical properties (strength, creep resistance, etc.) is a known good ceramic material.
        Hot-pressing sintering, pressureless sintering, hot isostatic pressing sintering material, the high temperature strength can be maintained to 1600 ℃, the material is ceramic material of high temperature strength. The oxidation resistance is also good in all non oxide ceramics.
