Product Description

High Purity 99.2% Aluminium Oxide White Fused Alumina 0-1mm , 1-3mm for Refractory

1. Product Description of Aluminium Oxide White Fused Alumina

White Fused Alumina(WFA) is  also named as white aluminium oxide,it  selects the industrial alumina

powder as raw material,melted in an electrical furnace under high temperature over 2000 degrees,

then finally made into different grain size through different process of crushing and reshaping,magnetic



It has the characteristics of dense texture,high hardness,high purity,good self-sharpness&grinding ability,

small heating power,high efficiency,acid and alkali corrosion resistance, high temperature resistance and

good thermal stability.

3. Main Application of Aluminium Oxide White Fused Alumina

High grade refractories such as castables,Isostatic pressed refractoriesPre-cast refractory etc.

Bonded brasives:resin cutting discs,grinding wheels etc.;

Coated abrasives: sandpaper,sandbelts etc.;

Blasting media;

Grinding,polishing and lapping media.


4. Why White Fused Alumina is suitable for high grade refractoriess?

White Fused Alumina is obtained from the fusion of alumina in electric furnace under high

temperature over 2000°C,so it has good thermal stability and chemical stability, it is not only

able to keep the high temperature,but also maintain the dimensional stability after repeated

thermal cycling.
