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.

Comparing with brown fused alumina, white aluminum oxide is also characterized by its high purity, acid and alkali resistance, good thermal stability. Its the high grade refractory materials.


Fused White Alumina advantages:
1, High grade processed alumina as raw material.
2, High hardness, big specific gravity,
3, Good chemical stability and unique self-sharpening
4, Acid-alkali and corrosion resistance
5, Temperature tolerance
6, Higher efficiency and good thermal stability


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
