The aspects that quality of white corundum depends on:
1. The quality of white corundum firstly determines the degree of smelting, whether it is smelted thoroughly, and whether it contains raw materials.
2. The chemical Al2O3 of white corundum . the Al2O3% is higher, the hardness will be higher accordingly.
3. Particle size distribution refers to the span and concentration of the particle size, the smaller the particle size span, the more concentrated, the better the sandblasting polishing effect, and vice versa.
