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