P Series: P16-P2500, 27 Grit Numbers
F Series: P14-P1200, 30 Grit Numbers

4.~Advantages
1). Corrosion resistance, high strength, high hardness.
2). Good wear-resisting performance,resist to shock.
3). It is a cost-effective substitute for Ferrosilicon.
4).It costs less than ferrosilicon and carbon combination.
5). It has no dust nuisance while feeding the material.
6). It can speed up the reaction. 

5.~Applications
The abrasive tools made from China Black Silicon Carbide Abrasive for Refractory is applicable to non-ferrous materials with tensile strength, such as nonferrous metals, wood, leather, plastic, rubber, stone material, gray cast iron, silicate materials(glass, ceramic, concrete and refractory matter), etc. Adding a proper amount of black silicon carbide as deoxidant during the smelting of steels can significantly improve the quality of steels. Due to its heat resistance, resistance to chemical attack and thermal shock resistance, it is widely used in high quality refractory matter and other industries.
