Green black silicon carbide powder
Green black silicon carbide powder:
Black silicon carbide (SiC) is an extremely hard (Mohs 9.1 / 2550 Knoop) artificial mineral with high thermal conductivity and strength at high temperatures (SiC is 7.5 times stronger than Al2O3 at 1000 ° C). SiC has a modulus of elasticity of 410 GPa, does not lose strength up to 1600 ° C and does not melt at atmospheric pressure, but dissociates at 2600 ° C.
