Cas No. :1344-28-1
Quantity: 9999 Specs:white aluminium oxide Price:666 USD Metric Tons Payment Method: 100% TT Factory electrically melting fused white aluminium oxide Fused 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. It can be made to the abrasives, suitable for sandblasting and grinding high carbon steel and staining steel and other fine-grained abrasive; also be used for precision casting and high-refractory materials. Physical properties Chemical compositions Value of specifications (%) Hexagonal Al2O3 ≥99.55 Main crystal body Al2O3 Color white Na2O ≤0.22 Grain density ≥3.9 g/cm3 Bulk density 1.75-1.95 g/cm3 SiO2 ≤0.03 Morse hardness ≥9 Linear expansion coefficient(1/°C) 8.3x10-4 Fe2O3 ≤0.04 Loss on ignition (%) ≤0.08 Performance and advantages for fused white aluminium oxide : 1. Not affecting the color of the processing cases; 2. Sandblasting in the non-iron process; 3. High speed processing and quality; 4. Containing a very low amount of iron oxide, suitable for non-ferrous blasting operations; |
