UK Aluminium Industry Fact Sheet 2 Aluminium and Corrosion
The physical-chemical stability of the oxide film determines the corrosion resistance of the aluminium. This stability is dependent upon the pH value of the environment, since the oxide film is stable within the pH range of about 4 to 8. Below and above theseAl3+

Aluminum Oxide Group Al2O3 - Panadyne Abrasives
Aluminum oxide comes in white, brown, and pink, each with slightly different properties. OSHA recommends Brown Al 2 O 3 as an alternative to silica sand, it is considered tough and durable with low friability and fast cutting. White Al 2 O 3 has high purity for technical appliions with high friability and will break down quickly exposing new edges.

Grinding Wheels - Orange Aluminum Oxide (Vitrified Bonded 38A) Features: Orange Aluminum Oxide Grinding Wheels are used on bench or pedestal grinders for high speed drill, tools and special steel.
Corrosion of aluminum
At lower and higher pH, aluminum is more likely to corrode but by no means always does so. For example, aluminum is quite resistant to concentrated nitric acid. When aluminum is exposed to alkaline conditions corrosion may occur, and when the oxide film is perforated locally, accelerated attack occurs because aluminum is attacked more rapidly than its oxide under alkaline conditions.
Spectroscopic evidence for Fe(II)-Fe(III) electron transfer …
Using the isotope specificity of 57Fe Mössbauer spectroscopy, we report spectroscopic observations of Fe(II) reacted with oxide surfaces under conditions typical of natural environments (i.e., wet, anoxic, circumneutral pH, and about 1% Fe(II)). Mössbauer spectra

Aluminum doped Zinc Oxide (AZO) is a highly insoluble thermally stable Aluminum source suitable for glass, optic and ceramic appliions. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding appliion in the hode of solid oxide fuel cells and oxygen generation systems.
EFFECT OF ANION, PH, AND TEMPERATURE ON THE …
The growth and dissolution behavior of oxide film on abraded pure Al has been investigated using cyclic polarization and has been found to be highly dependent on solution chemistry and temperature. The nature of the anions, borate, chromate, phosphate, and sulfate, at pH 3 to 11, and temperatures 0 to 60 C were examined. In near neutral solutions the dissolution behavior was greatly affected
Aluminum oxide is a compound composed of two aluminum atoms and three oxygens bonded together in a hexagonal close packed (hcp) crystal structure. The common name for the compound is alumina and it has found several appliions in the industry due to its abundance and abrasiveness.
