                                                                             White Fused Alumina   Description
White Fused Alumina was made from the high quality alumina by melting above 2000 °C in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

    .     Applications White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory materials.  
Advantages
1) Not affecting the color of the processing cases.
2) Sandblasting in the non-iron process.
3) High speed processing.
4) Very low amount of iron oxide, suitable for non-ferrous blasting operations.
