Why SiC Ceramic
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 have the best high temperature mechanical properties (strength, creep resistance, etc.) among known ceramic materials.
SiC is a kind of hot pressing sintering, non-pressing sintering, hot isostatic pressing sintering material, its high temperature strength can be maintained to 1600℃, is the best high temperature strength materials in ceramics, at the same time the oxidation resistance is also the best of all non-oxide ceramics.

Applications
The initial application of SiC is due to its super hard, can be prepared into a variety of grinding wheel, emery cloth, sandpaper and all kinds of abrasive, so widely used in the machining industry. In the Second World War, it was found that it could also be used as a reducing agent and heating element in steelmaking, thus promoting the rapid development of SiC.
SiC ceramics in petroleum, chemical industry, microelectronics, automotive, aerospace, aviation, paper, laser, mining and atomic energy and other industrial fields have been widely used, silicon carbide has been widely used in high temperature bearing, bulletproof plate, nozzle, high temperature corrosion resistant parts and high temperature and high frequency range of electronic equipment parts and other fields.
