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

It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has. Activated alumina in its phase composition can be represented only by metastable forms (gamma-Al 2 O 3 etc.). Corundum (alpha-Al 2 O 3), the only stable form of aluminum oxide, does not have such a chemically active surface and is not used as a ...
Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has the characteristic physical properties of a post-transition metal, with longer-than-expected interatomic distances. [1] Furthermore, as Al 3+ is a small and highly charged cation, it is strongly polarizing and aluminium compounds tend towards ...
Aluminium oxide is an amphoteric oxide of aluminium with the chemical formula Al 2 O 3. It is also commonly referred to as alumina or aloxite [1] in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite.
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 ...
