Cas No. :28-18-2
Aluminium Oxide (Al2O3), by the bauxite industry Al2O3 (Al2O3▪3H2O) and diaspore prepared for the high purity requirements of Al2O3, generally chemically prepared.
Al2O3 many allomorphs, now known to have 10 kinds, there are three kinds of crystal forms, namely γ-Al2O3, β-Al2O3, α-Al2O3. Wherein the different structural properties is different, at a high temperature above 1300 ℃ almost complete conversion of α-Al2O3.It insoluble in water, solid white, odorless, tasteless, quality extremely hard, not easy to absorb moisture deliquescence (calcined, non-hygroscopic). Amphoteric oxide, soluble in inorganic acid and alkaline solution, almost insoluble in water and non-polar organic solvent; the relative density (d204) 4.0; melting point 2050 ℃. Basic Information: Chinese name: Alumina Nickname: aluminum oxide, corundum, alumina, aluminum oxide English name: Aluminium oxide / Aluminum oxide Main Purpose: Vehicle Alumina powder commonly pornographic layer analysis of vehicle. Manufacturing tempered glass Alumina is an aluminum metal in the air is not easy to corrosion reasons. Aluminum oxide film covering pure aluminum easily with oxygen in the air reacts in a thin layer of aluminum surface exposed to air. This layer of aluminum oxide film to prevent oxidation of the aluminum is continuing. Processing and properties of the oxide film thickness can be called by anodization (anode corrosion) has been strengthened. Applicable range of industries: aerospace, automotive industry, consumer goods, processing, casting / die casting, OEM distributors, the semiconductor industry and other various fields. Applicable range of technology: surface plating, painting, glazing and coating polytetrafluoroethylene before pretreatment; and aluminum alloy products, deburring, boiler scale; mold cleaning; metal substrates before blasting; dry and wet; precision optical refraction; minerals, metals, glass and crystal grinding; glass sculpture and paint additives. |
