Calcium selenide (CaSe) is a chemical compound consisting of the elements calcium and selenium in equal stoichiometric ratio.[1]

Preparation and properties

Calcium selenide can be prepared via the reaction of calcium and H2Se in liquid NH3.[2]

Ca + H2Se → CaSe + H2

Calcium selenide reacts with indium(III) selenide in vacuum at high temperature to give CaIn2Se4.[3]

CaSe + In2Se3 → CaIn2Se4
