White Fused Aluminum Oxide Aggregate 3-5mm 5-8mm
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.
