Infobox references

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.
