Aluminium selenide is the inorganic compound with the formula Al2Se3.

Preparation

It is a solid prepared by igniting a mixture of the elements at Шаблон:Convert:

2 Al + 3 Se → Al2Se3

The pure compound is white, but typical samples are coloured.[1] Samples are usually protected from moisture, because they hydrolyze readily, giving off highly toxic hydrogen selenide gas:[2]

Al2Se3 + 3 H2O → Al2O3 + 3 H2Se

Use

Al2Se3 has been used as a precursor to hydrogen selenide, which is released when the solid is treated with acids.[1]
