Complaint
Green silicon carbide is produced by smelting petroleum coke and high-quality silica in an electric resistance furnace at high temperature. The refined crystal has high purity, high hardness, hardness between corundum and diamond, and mechanical strength is higher than corundum.The SiC purity of green silicon carbide is up to 99%min.With high thermal conductivity and high strength which get no decrease in 1000 centigrade.
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
