Barium selenide is an inorganic compound, with the chemical formula of BaSe. It is a white solid although typically samples are colored owing to the effects of air oxidation.
BaSe has the lowest energy band gap among alkaline earth chalcogenides.
Preparation
Barium selenide can be obtained by the reduction of barium selenate in hydrogen flow:.
BaSeO4 + H2 → BaSe + 4 H2O
It can also be obtained by reacting selenium with barium carbonate or barium oxide at high temperature:
2 BaCO3 + 5 Se → 2 BaSe + 3 SeO2 + CO2
Related compounds
Barium can also forms a series of polyselenide compounds, such as Ba2Se3, BaSe2 and BaSe3.
