Barium selenide is an inorganic compound, with the chemical formula of BaSe. Barium can also form other compounds, such as Ba₂Se₃, BaSe₂ and BaSe₃.[2][3] BaSe has the lowest energy band gap among alkaline earth chalcogenides.[4]

Preparation

Barium selenide can be obtained by the reduction of barium selenate in hydrogen flow:[5]

BaSeO₄ + H₂ → BaSe + 4 H₂O

Barium selenide can also be obtained by reacting selenium with barium carbonate or barium oxide at high temperature:[2]

2 BaCO₃ 5 Se → 2 BaSe + 3 SeO₂ + CO₂
