Aluminium(I) oxide - Wikipedia
Aluminium (I) oxide is a compound of aluminium and oxygen with the chemical formula Al 2 O. It can be prepared by heating the stable oxide Al 2 O 3 with elemental silicon at 1800 °C under vacuum. [1] Al 2 O commonly exists as a gas, since the solid state is not stable at room temperature and is only stable between 1050 and 1600 °C.
