Product Feature of 98% SiC 0一1mm Black silicon carbide
- Good oxidation resistance and chemical stability at high temperatures.
- High hardness with Mohs 9.2-9.3. Even at 2000℃, it’s still getting high strength.
- Excellent toughness.
- Low thermal conductivity. So it can resistant to thermal shock.
- High purity min SiC content is 98.5%.
- High bulk density.
- Black silicon carbide grit is washed by water before the milling process, so there are few impurities.
