Green Silicon Carbide
Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600
Knoop) man made mineral that possesses high thermal conductivity
and high strength at elevated temperatures (at 1000°C, SiC is 7.5
times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in
strength up to 1600°C, and it does not melt at normal pressures but
instead dissociates at 2600°C.
