White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency.
White fused aluminum oxide becomes the first choice for the sandblasting , meanwhile, it is also the ideal material for abrasive and work piece cleaning, and polishing.
Comparing with brown fused alumina, white aluminum oxide is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.
White aluminum oxide for refractory advantages:
1.No ferric contamination
2.Strict control of size distribution and other physical and chemical properties
3.Excellent thermo - mechanical properties, thermal shock resistance
4.High volume stability
5.High density, low permeability for producing high refractoriness
6.High chemical resistance and chemical stability
7.Abrasion resistant and high wear-resistant
8.Good corrosion properties
9.High mechanical stability and strength
