Green silicon carbide grit is a very hard abrasive material . The hardness of it only ranks after diamond and B4C, and it is harder than black silicon carbide. So it is suitable to grinding large range of hard material such as titanium alloy, marble, carbide alloy, optical glasses, ceramics, etc. Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. The SiC purity of green silicon carbide is up to 99%min. It is an artificial brittle SiC with high thermal conductivity and high strength which get no decrease in 1000 centigrade.
