Black silicon carbide blast media 98% sand & powder F12-F220 HAIXU Abrasives

Black silicon carbide blast media 98% sand & powder F12-F220 is an artificial abrasive made of carbonaceous materials and siliceous materials through high-temperature smelting in a large resistance furnace. The carbonaceous material is petroleum coke or coal coke. And the siliceous material always goes quartz sand. At the same time, the smelting process will also add wood chips, salt and other additives.

The purity of the silicon carbide of the first-grade black silicon carbide is more than 98%. The color is shiny, and the reflection shows multicolored colors. Generally, the higher the purity of silicon carbide, the better its physical and chemical properties. The hardness of black silicon carbide is slightly lower than that of green silicon carbide, with a Mohs hardness of 9.2-9.3. Haixu black silicon carbide grit is produced by crushing, washing, screening, magnetic separation and other processes from first-grade silicon carbide blocks. It ha

Product Feature of Black silicon carbide blast media 98% sand & powder F12-F220

1. Good oxidation resistance and chemical stability at high temperatures.
2. High hardness with Mohs 9.2-9.3. Even at 2000℃, it’s still get high strength.
3. Excellent toughness.
4. Low thermal conductivity. So it can resistant to themal shock.
5. High purity min SiC content is 98.5%.
6. High bulk density.
7. Black silicon carbide grit is washed by water before milling process, so there is few impurities.
