Green Silicon Carbide SiC 98% High Purity for Surface Treatment of Glass and Ceramics
Green Silicon Carbide Introduction
Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. It is a synthetic brittle carborundum with high thermal conductivity and high strength which get no decrease in 1000℃( 7.5 times stronger than Alumina)
Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only ranks after CBN and B4C.
