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 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)
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 ...

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 −
The market of boron carbide is steadily growing between the period 2025-2035 because its application across highly critical sectors has increased considerably to date. With respect to many properties like superior hardness, being light, heat-resistant, it provides innumerable potential applications that help the sector's growth significantly.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
