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(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 industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4), which is used in as a reducing agent in organic chemistry. It can be produced from lithium hydride and aluminium trichloride: [25] 4 LiH + AlCl 3 → LiAlH 4 + 3 LiCl. The simplest hydride, aluminium hydride or alane, is not as important.
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.

The most common methods in current use are electroplating, chemical "wet process" deposition, and vacuum deposition. Electroplating of a substrate of glass or other non-conductive material requires the deposition of a thin layer of conductive but transparent material, such as carbon. This layer tends to reduce the adhesion between the metal and ...
Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores. The diameter of the pores can be as low as 5 nanometers and as high as several hundred nanometers, and length can be controlled from few ...
