Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
Aluminium(I) oxide (Al 2 O) Aluminium(II) oxide ( AlO ) (aluminium monoxide) Aluminium(III) oxide (aluminium oxide), ( Al 2 O 3 ), the most common form of aluminium oxide, occurring on the surface of aluminium and also in crystalline form as corundum , sapphire , and ruby .
Aluminium(I) oxide is a compound of aluminium and oxygen with the chemical formula Al 2 O. It can be prepared by heating the stable oxide Al 2 O 3 with elemental silicon at 1800 °C under vacuum .
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Aluminium forms one stable oxide with the chemical formula Al 2 O 3, commonly called alumina. [15] It can be found in nature in the mineral corundum, α-alumina; [16] there is also a γ-alumina phase. [13]

Aluminium(II) oxide or aluminium monoxide is a compound of aluminium and oxygen with the chemical formula AlO. It has been detected in the gas phase after explosion of aluminized grenades in the upper atmosphere [ 1 ] [ 2 ] [ 3 ] and in stellar absorption spectra.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
