   Gong Yi Hui Yuan White Fused Alumina Natural Abrasive                              

                                                    

White Fused Alumina, a kind of high-grade refractories, 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. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

 

Advantage:

1. White fused alumina has Al2O3 content around 99% min, also we passed the certification of ISO9001
2. All products will be supplied according to customers different requirement
3. The output is huge and stable
4. The chemical and physical analysis:

Model:JIS#150
