Best Green SiC & Black SiC

Silicon Carbide (SiC) is a hard (Mohs 9.4 / 2600 Knoop) human-made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3).
Silicon Carbide is produced in electrical internal resistance furnaces from very high purity silica sand and petroleum coke. Hexagonally shaped, it breaks into very sharp particles. Green SiC is harder than black SiC,
The color difference is due to the purity of the silicon carbide, green SiC being higher purity due to its closer proximity to the furnace’s heat source.
