Aluminium(II) oxide oraluminium monoxide is a compound ofaluminium andoxygen with thechemical 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 thealuminium oxides (the most common isaluminium oxide Al2O3), as it was the rare example of an aluminium(II) compound since aluminium usually exists in its +3oxidation state.
Aluminium is an unstable compound, due to it easily reacting with oxygen to become aluminium(III) oxide:[5]
