aluminium oxides - wikipedia
Aluminium oxides. Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium (III) oxide (aluminium oxide), ( Al2O3 ), the most common form of aluminium oxide, occurring on the surface of aluminium and also in crystalline form as corundum, sapphire, and ruby. This set ...
aluminium oxide: properties, production, and applications ...
Aluminium oxide is an inert, odourless, white amorphous material that is used in various industries owing to its exquisite thermal, mechanical, and chemical properties. It is also known as alumina, and exists naturally as corundum or bauxite.

Note: * aluminum oxide in α-form. ** — no data. Obtaining of aluminum oxide: Aluminium oxide obtained by reduction with aluminium metals from their oxides: chromium, molybdenum, tungsten, vanadium, etc. (metallothermy). It is obtained the following metallotrejderskih reactions:. Cr2O3 + 2Al → Al2O3 + 2Cr (t = 800 oC);
aluminium oxides - an overview | sciencedirect topics
Calculated as an oxide, aluminium constitutes around 15.3 wt% of the non-water content of the earth’s crust (Weast, 1974). The primary ore of relevance to the aluminium industry is bauxite, a mixture of aluminium hydroxides and oxyhydroxides, accompanied by varying amounts of iron oxides, silicates and other impurities.
aluminium(i) oxide - wikipedia
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 is difficult to detect and identify. In reduction, Al 2 O is a major component of vapors ...
