It has been detected in the gas phase after explosion of aluminized grenades in the upper atmosphere [1] [2] [3] and in stellar absorption spectra. [4] Aluminium(II) oxide is one of the aluminium oxides (the most common is Aluminium oxide Al 2 O 3), as it was the rare example of aluminium(II) compound since aluminium usually exists in its +3 ...

Its density is also lower than that of liquid aluminium (2 vs 2.3 g/cm 3), which allows natural separation of the product from the salt at the bottom of the cell. The cryolite ratio (NaF/AlF 3 ) in pure cryolite is 3, with a melting temperature of 1010 °C, and it forms a eutectic with 11% alumina at 960 °C.
For example, aluminium monoxide, AlO, has been detected in the gas phase after explosion [19] and in stellar absorption spectra. [20] More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand. [21]
The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3), selenide (Al 2 Se 3), and telluride (Al 2 Te 3). All three are prepared by direct reaction of their elements at about 1,000 °C (1,800 °F) and quickly hydrolyze completely in water to yield aluminium hydroxide and the respective hydrogen chalcogenide .

The density of liquid aluminum is 2.3 g/ml at temperatures between 950 and 1000 °C (1750° to 1830°F). The density of the electrolyte should be less than 2.1 g/ml, so that the molten aluminum separates from the electrolyte and settles properly to the bottom of the electrolysis cell.
