Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials through high-temperature resistance furnace smelting. Silicon carbide is also called moissanite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical type, which can be called gold steel sand or refractory sand
Application
1. Silicon carbon be used as metallurgical deoxidizer and high temperature resistant material in smelting.
2. It can also be used as grinding material,can be used to manufacture grinding tools,such as grinding wheel,whetstone,grinding head.
Advantages
1.corrosion resistance,high strength,high hardness,
2.good wear-resisting performance,resist to shock
3.stable chemical performance,high thermal conductivity,high resistant temperature
