Product Description
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.
The production method of green silicon carbide is the same as that of black silicon carbide. It is formed at a high temperature of about 2200 °C. Green, translucent, hexagonal, with a higher Sic content than black. The smelted crystal has high purity and high hardness, and the hardness is between alumina and diamond. The mechanical strength is higher than that of alumina. The physical properties are similar to black silicon carbide, but the performance is slightly brittle than black, and it also has better thermal conductivity and semiconductor properties.
