Silicon carbide (SiC) is made from quartz sand and petroleum coke or coal tar, wood chips and other raw materials by smelting in high temperature electric resistance furnace . In the high technology non-oxide refractory raw materials , such as C, N, B ,ilicon carbide is the most widely used and one of the most economic material. It can be called corundum or refractory sand.
Silicon Carbide Characteristics
1.small thermal expansion
2.high thermal conductivity
3.not easy to have thermal stress
4.good thermal shock resistance
5.corrosion resistance
6.extreme cold or heat
7.high temperature creep resistant ability
