Aluminium(II) oxide explained

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 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 Al₂O₃), as it was the rare example of aluminium(II) compound since aluminium usually exists in its +3 oxidation state.
