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
separation,screening.
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.
