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.
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.
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 ...
Corundum. Corundum is a crystalline form of aluminium oxide (Al2O3) typically containing traces of iron, titanium, vanadium, and chromium. [3][4] It is a rock -forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Aluminium (I) compounds. In chemistry, aluminium (I) refers to monovalent aluminium (+1 oxidation state) in both ionic and covalent bonds. Along with aluminium (II), it is an extremely unstable form of aluminium. While late Group 13 elements such as thallium and indium prefer the +1 oxidation state, aluminium (I) is rare.
Network covalent bonding. A network solid or covalent network solid (also called atomic crystalline solids or giant covalent structures) [1][2] is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. In a network solid there are no individual molecules, and ...
Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character.
Aluminium (II) oxide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Aluminium (II) oxide or aluminium monoxide is a compound of aluminium and oxygen with the chemical formula AlO. It has been detected in the gas phase after explosion of aluminized grenades in the upper ...
