High Purity Abrasive Aluminum Oxide Powder

Product DescriptionAlpha Aluminum Oxide Alumina Powder for PolishingAlumina powder, also known as aluminium oxide or activated alumina, is a chemical compound that is mainly used to produce aluminium.Alumina powder is the ideal for aluminium production and others that require hardness and resistance to abrasion or other forms of chemical wear. Alumina powder is also ideal for products that require corrosion and wear resistance, and for products that requirehigh thermal conductivity, such electrically and thermally insulating applications.Physical and Chemical Indicators  Physical Properties:ColorWhiteAppearancePowderMohs hardness9.0-9.5Melting point (ºC)2050Boiling point (ºC)2977True density3.97 g/cm3   Grains0.3μm, 0.5μm, 0.7μm, 1.0μm, 1.5μm, 2.0μm, 3.0μm, 4.0μm, 5.0μmSpecificationsAI2O3Na2OD10(um)D50(um)D90(um)The original crystal grainspecific surface area(m2/g)0.7um≥99.6≤0.02>0.30.7-10.51-1.80.82.0-3.0
