Reaction Bonded Silicon Carbide
Reaction bonded sintered silicon carbide (RBSiC) products — an economical grade with excellent wear characteristics and good chemical resistance for medium acid or mild alkaline medium.
Overview
About Reaction Bonded Silicon Carbide
Reaction bonded sintered silicon carbide is made from fine particles of silicon carbide and additive compressed into billet, at 1500 °C to 1800 °C high temperature vacuum contact with liquid silicone, free silicon filling the pores, and high density of ceramic material is obtained. It can be used in medium acid or mild alkaline medium. It can be at medium concentration of acid or used in mild alkaline medium, it is widely used in bearing and oil, chemical, automobile and ship, pump valve and other fields.
