Black silicon carbide grain & black silicon carbide powder are widely used as sandblasting grit, polishing powder, and raw material for coated abrasive tools. High-quality black silicon carbide grain is durable of good grinding ability for those applications. There are several characteristics with high-quality silicon carbide abrasive material:
Firstly, the content of high-quality and dense silicon carbide products is more than 98%:
| SiC | Fe2O3 | F.C. | |
| P12-220 | ≥99.50 | ≤0.10 | ≤0.15 |
| P240-400 | ≥99.00 | ||
| P500-1200 | ≥98.50 | ||
| P1500-3000 | ≥98.00 | ≤0.20 |
Secondly, high bulk density and good particle shape.
The specific gravity is min 3.2g/m3
The bulk density is min 1.62g/m3.
The black silicon carbide from HAIXU is made by the ball milling process. Thus, it gets a good particle size. So it could improve the grinding alibility.
Moreover, high cleanness
Good quality black silicon carbide is with very small impurity pollution and content of free carbon.
Haixu high-quality black silicon carbide is treated by an acid washing process. It removes impurities and free carbon. And then, get a very clean material. We have more than 20 years of experience in manufacturing. The quality was approved by many customers both from local China and abroad.
