White fused alumina is a kind of high-grade refractories, it is made from the imported high alumina by smelting above 2000℃ in the dumping type electric arc furnace and cooling. It is white with the main crystal phase a-Al2O3.
Features:
1. High bulk density.
2. Low porosity.
3. Good volume stability and thermal shock resistance.
Application:
1. Refractories: White fused alumina is suitable for shaped and amorphous refractories in iron and steel industry, cement industry, ceramics petrochemical industry, etc., such as large ladle castables, gunning material, precasting block, corundum brick, corundum refined porous plug bricks, lining material for blast furnace, etc.
2. Abrasives: White fused alumina is used for consolidation and coating abrasives, wet or dry sprayed grit, ultra-precise grinding and polishing in the crystal and electronic industry.
