Instructions for use of White fused alumina powder/white corundum

The fused white corundum is made of high-quality alumina powder and is electrolyzed and refined. Its hardness is slightly higher than that of brown corundum. It has slightly lower toughness, high purity, good self-sharpness, strong grinding force and low calorific value. High efficiency, acid and alkali corrosion resistance, high temperature resistance and good thermal stability. It is used to make abrasive tools, which are suitable for cutting carbon, high speed and just high. It can also be used as grinding, polishing materials, precision casting, spray materials, chemical catalyst carriers, special ceramics, advanced refractories, etc.

Production process of White fused alumina powder/white corundum

White fused alumina powder/white corundum is a medium-to-high-grade refractory raw material with white color and dazzling appearance. The white corundum has the advantages of large bulk density and low porosity, which can effectively improve the volume stability and thermal shock resistance of the material. The fused white corundum is the main raw material for the production of high-grade indefinite and shaped refractory materials. It is used for large-scale ladle castables, medium and high-grade iron trench castables, spray materials, prefabricated parts and other amorphous refractories and corundum bricks, corundum and Mullite corundum body, refining corundum porous plug brick, integral spray gun and composite nozzle, high temperature industrial kiln lining and other corundum products. Widely used in steel, cement, ceramics, abrasives, petrochemical and other industries.

Product Features

Advantages of White fused alumina powder/white corundum as abrasive

1. Does not affect the color of processed parts;

2. It can be used for sandblasting in a process where iron powder residue is strictly prohibited;

3. The micro powder level is very suitable for wet sandblasting and polishing operations;

4. Fast processing speed and high quality;

5. The amount of iron oxide contained is extremely low, suitable for sandblasting operations where iron residues are strictly prohibited;

6. After pickling step to remove impurities.
