Black Silicon Carbide (SiC)
|
|
Description
|
Black Silicon Carbide (SiC) is an extremely hard (Mohs 9.1/ 2550 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 Al203 ). 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.
