Description:

White fused aluminum oxide refractory (White corundum), was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. White corundum is a high-level refarctroy raw material with Al2O3 purity up to 99%.It can work as refractory castable, aggregate,refractory coating etc.

  

Characteristic:

With smelting point up to 2250℃, white aluminum oxide is a high level refractory material. It has advantages including high purity,good acid-alkali resistance, temperature resistance, high thermal stability.

 

Applications:

Refractory castable and aggregate.

Kiln construction.

Furnace building.

Refractory coating paint.

Coating sand for Precision casting and 3D printing.

Ceramic Tiles special ceramics.

Technical ceramics.
