Aluminium oxide -
Aluminium oxide (or Aluminium (III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. 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
Atomic-Scale Insights into the Oxidation of
On Al(111) the oxide was observed to grow into the aluminum lattice beneath the island, with part of the aluminum surface starting to exfoliate, rotating 10° relative to the bulk. This can be explained by the high dynamic stresses that are generated in amorphous oxides due to free volume generation (compared to bulk
Aluminium(I) oxide -
Aluminium(I) oxide is formed by heating Al and Al 2 O 3 in a vacuum while in the presence of SiO 2 and C, and only by condensing the products. Information is not commonly available on this compound; it is unstable, has complex high-temperature spectra, and

4.4: Oxidation-Reduction Reactions - Chemistry
Each neutral aluminum atom loses three electrons to produce an aluminum ion with an oxidation state of +3 in the product, so aluminum has been oxidized. In the formation of Al 2 O 3, electrons are transferred as follows (the small overset number emphasizes the oxidation state of the elements): (4.4.3) 4 Al 0 + 3 O 2 0 → 4 Al 3 + + 6 O 2

Adsorption and oxide formation on aluminium
As the film thickens it changes from covalent amorphous to ionic spinel character, and the activation energy for place exchange increases. The process of film growth in the ionic film (thickness > ca. 10 Å) involves electron tunnelling and cation
