SIC ceramic features not only has high room temperature strength, corrosion resistance, wear and low friction coefficient, and has a high temperature strength and creep resistance, the use of temperature up to 1600 ℃, is currently known ceramic materials in high temperature oxidation , The best strength of the material. The disadvantage is brittle, fracture toughness is low. The use of fiber, whiskers and particles can enhance the strength and strength of SiC ceramics. Can be widely used in petroleum, chemical, automotive, aerospace, electronics, atomic energy and other fields, for high temperature, wear resistance, corrosion resistance, sealing, electronic packaging and other materials.
