Aluminium selenide is the inorganic compound with the formula Al2Se3.
It is a solid prepared by igniting a mixture of the elements:
The pure compound is white, but typical samples are coloured. Samples of aluminium selenide must be protected from moisture, because the compound hydrolyzes readily, giving off highly toxic hydrogen selenide gas:
Al2Se3 has been used as a precursor to hydrogen selenide, which is released when the solid is treated with acids.
