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
The alloy Aluminum is also needed because if Aluminium is not stabilized, it will corrode and degrade right back into Aluminium Oxide as it interacts with moisture in the air. Aluminium Oxide is neither Aluminium nor Aluminum, but a white worthless dust you could call a rust. Similar to iron rust.
Oxidizing acids do not effectively attack high-purity aluminium because the oxide layer forms and protects the metal; aqua regia will nevertheless dissolve aluminium. This allows aluminium to be used to store reagents such as nitric acid , concentrated sulfuric acid , and some organic acids.
Particles of refractory material in contact with aluminium can detach and become inclusions. We can find graphite inclusions (C), alumina inclusions (alpha-Al 2 O 3), CaO, SiO 2, … After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions).

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.
