white aluminum oxide F220 for abrasives and sandbl

1.Product Description 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.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 and physical parameters Model: white aluminum oxide F220 Chemical compositions Physical properties Items Value of specification (%) Items Property Al2O3 99.53min Color White SiO2 0.04max Bulk density 1.75-1.95g/cm3 Na2O 0.25max Grain density 3.90g/cm3 min Fe2O3 0.04max hardness Morse hardness 9 Micro hardness 21600-22600kg/mm3 Usage abrasives and sandblasting content of magnetic substance 0.0023%max 3.Mills White Fused Alumina plants Brown Fused Alumina plants Mullite plants 4.Performance and advantages 1.
