| Silicon carbide is the most corrosive of all advanced ceramics. It still retain its at temperatures up to 1400 ℃ high strength, and provide excellent wear resistance and thermal shock resistance. Silicon carbide materials have high hardness, high wear resistance and chemical resistance. High heat conductivity, stable performance at high temperature, high temperature structure material. | ||||
