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 ...
However, the capacity of NCA is significantly higher than that of alternative materials such as lithium cobalt oxide LiCoO 2 with 148 mAh/g, lithium iron phosphate LiFePO 4 with 165 mAh/g and NMC 333 LiNi 0.33 Mn 0.33 Co 0.33 O 2 with 170 mAh/g. [2] Like LiCoO 2 and NMC, NCA belongs to the cathode materials with layer structure. [1]
Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium(I) oxide ( Al 2 O ) Aluminium(II) oxide ( AlO ) (aluminium monoxide)
Aluminates are often formulated as a combination of basic oxide and aluminium oxide, for example the formula of anhydrous sodium aluminate NaAlO 2 would be shown as Na 2 O·Al 2 O 3. A number of aluminate oxyanions are known: The simplest is the approximately tetrahedral AlO 5− 4 found in the compound Na 5 AlO 4, [2] framework AlO −
Corundum is the name for a structure prototype in inorganic solids, derived from the namesake polymorph of aluminum oxide (α-Al 2 O 3). [1] Other compounds, especially among the inorganic solids, exist in corundum structure, either in ambient or other conditions.
Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, in sulfur removal from fluid streams (Claus Catalyst process).

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. [2] 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 ...
