Глинозем высокой чистоты порошок белого плавленого глинозема / МФО

1.Product Description white fused alumina powder,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. 2.Chemical and physical parameters Model:white fused alumina powder JIS#3000 Chemical compositions Physical properties Items Value of specification (%) Items Property Al2O3 99.10min Color White SiO2 0.04max Bulk density 1.75-1.95g/cm3 Na2O 0.35max Grain density 3.90g/cm3 min Fe2O3 0.06max hardness Morse hardness 9 Micro hardness 21600-22600kg/mm3 Usage Polishing ,sandblasting and grinding content of magnetic substance 0.0023%max 3.Mills White Fused Alumina plants Brown Fused Alumina plants silicon carbide plants Mullite plants 4.Performance and advantages 1.
