Reaction-Bonded Silicon Carbide (LY101(SiSiC))

Reaction-Bonded Silicon Carbide (LY101(SiSiC)) is produced by mixing SiC powder with powdered carbon and a plasticizer, forming the mixture into the desired shape, burning off the plasticizer, and then infusing the fired object with free silicon and additive in a vacuum sintering furnace at 1500°C. Reaction sintered silicon carbide has the characteristics of good lubricity, small friction coefficient and wear resistance. It can be used to make bearings and sealing rings and is widely used in the fields of petroleum, chemical, automobile, ship, pump and valve.
