Refractory Grade White Corundum Hexagonal Crystal 3.50 Min G/Cm3 Density

White Fused Alumina

Raw Material And Process Of Production:

White fused aluminum oxide also named white corundum

White fused alumina / White Corundum is high grade refractory material , which made from the high quality alumina by melting above 2000 ℃ in the electric arc furnace and cooling. classify into different parcel size.

Product Performance

White fused alumina Occupying higher hardness and slightly lower toughness compared with Brown Fused Alumina, it is characterised by its high purity, better cutting,ability of self-sharpening, less heat emit during grinding, higher efficiency,acid and alkali resistance, and good thermal stability. Abrasive tools made of it are suitable for grinding high-speed, high carbon steel,etc.


* For precision casting and high-grade refractory.

* For bake lining ,Catalyst carrier ,friction products

* For pressure blasting hard abrasives;Refractory industry

* For wet and dry blasting ,grinding,lapping and polishing media

* For abrasive tools: grinding wheel, Lapping and polishing non-skid title;

* For bonded and Coated abrasives ,Thermal Spraying (Plasma Spraying)

* For lapping & Micro-Blasting applications .refractories,Ceramics and Tiles .

Use of white fused alumina powder:

The abrasive tools made for high carbon steel, Taiwan steel, high-speed steel and hardened steel and other hard grinding material, tensile strength is larger. It is suitable for fixing structure and coated abrasives, wet or dry spray sand, crystal, ultra precision grinding and polishing of the electronics industry and the production of high-level refractory materials.

Can also be used as grinding and polishing materials, precision casting molding sand, spraying materials, chemical catalyst carrier, special ceramics, advanced refractory materials, etc., it is characterized by strong cutting force, good chemical stability, good insulation
