White fused alumina Definition: A kind of artificial abrasive. the content of Al2O3 is over 98%, and containing a small amount of ferric oxide, silicon oxide. White fused alumina is high grade refractory material, which made from the high quality alumina by melting above 2000℃ in the electric arc furnace and cooling. Chemical Composition of White Fused Alumina: Al2O3 99.65% Na2O 0.25% Fe2O3 0.04% SiO2 0.03% Abrasives Grade: Grit Size Al2O3 Na2O F12-220 >99.5% <0.35% F230-400 >99.2% <0.4% F500-1200 >99.0% <0.5% Refractory Grade: Grit Size Al2O3 Na2O 0-1mm >99.2% <0.4% 1-3mm >99.2% <0.4% 3-5mm >99.2% <0.4% 200mesh >99.0% <0.5% 325mesh >99.0% <0.5% Application:  1.    White fused alumina powder is used for making abrasive tools 2.    White fused aluminum oxide grit could also used as refractory materials  3.    White fused aluminum oxide  could be used as grinding, lapping, polishing and blasting media
