white fused alumina micropowder high purity

SpecificationsWhite fused alumina powder 1.High purity of 99%min 2.hot sale overseas 3.manufacturerDescription: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.1.Advantages: a. Use imported Bayer aluminum; assure the high quality of products. b. Equipped full line of test method. The laboratory is certified by government Inspection Bureau, that assures its quality stability. c. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements.2.Chemical Analysis:Al2O3Fe2O3Na2OSiO2CaOK2O≥99.2%≤0.08%≤0.30% 120# Finer ≤0.40%≤0.10%≤0.03%≤0.03%5.Physical Analysis:CrystalTrue Density g/cm3Hardness Kg/mm2Melting PointRefractorinessMax Usable Temperatureα- Al2O3≥3.962000 22002000≥18501900
