Detailed Product Description
White aluminium oxide:
1. Manufacturer;
2. Al2O3: 99.55 min;
3. For spraying;
4. Hot sale overseas.
Description
White aluminium oxide is made from high quality alumina by melting above 2000°C in the electric arc furnace and then cooling. It is with high purity, great self-sharpening, acid and alkali resistance, high temperature and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency.
