1.Introduction: White Fused Alumina (WA), 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. 2.Chemical composition Items Value of specification(%) Al2O3 99.53min SiO2 0.04max Na2O 0.25max Fe2O3 0.04max3.Physical property Items Property Color White Bulk density 1.75-1.95g/cm3 Grain density 3.90g/cm3min Morse hardness 94.About us HenanHuanhe IndustrialCo., Ltd., has been specializing in abrasives and machinery for over 10 years and enjoys a good reputation for our best quality and service.Our company has passed ISO9001 Quality Management system Attestation.
