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(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.
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 oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium(I) oxide ( Al 2 O ) Aluminium(II) oxide ( AlO ) (aluminium monoxide)
The lower the position of a metal's line in the Ellingham diagram, the greater is the stability of its oxide. For example, the line for Al (oxidation of aluminium) is found to be below that for Fe (formation of Fe 2 O 3) meaning that aluminium oxide is more stable than iron(III) oxide. Stability of metallic oxides decreases with increase in ...

For example, aluminium monoxide, AlO, has been detected in the gas phase after explosion [19] and in stellar absorption spectra. [20] More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand .
For example, aluminium oxide Al 2 O 3 and phosphorus(III) oxide P 4 O 6 are sesquioxides. Many sesquioxides contain a metal in the +3 oxidation state and the oxide ion O 2−, e.g., aluminium oxide Al 2 O 3, lanthanum(III) oxide La 2 O 3 and iron(III) oxide Fe 2 O 3. Sesquioxides of iron and aluminium are found in soil.
