Aluminium Oxide (Al2O3), by the bauxite industry Al2O3 (Al2O3&©|9642;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 ¦Ã-Al2O3, ¦Â-Al2O3, ¦Á-Al2O3. Wherein the different structural properties is different, at a high temperature above 1300 ℃ almost complete conversion of ¦Á-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 ℃.

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.
