White Fused Alumina 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.
So its main chemical composition is aluminum oxide(Al2O3) which is 99%min,besides,have other small percentage of Sodium Oxide(Na2O),Ferric Oxide(Fe2O3) and so on.
Zhengzhou Haixu Abrasives Co.,ltd,has produced white fused alumina more than 20years,with the development of production technology,the quality of white fused alumina is improved year by year, for white fused alumina macrogrit,Al2O3 is 99.5%min. for micropowder,we take more advanced technical and make it higher purity and PSD more concentrated.
