Preparation and properties

Calcium selenide can be prepared via the reaction of calcium and H<sub>2</sub>Se in liquid NH<sub>3</sub>.

Ca + H<sub>2</sub>Se → CaSe + H<sub>2</sub>

Calcium selenide reacts with indium(III) selenide in vacuum at high temperature to give CaIn<sub>2</sub>Se<sub>4</sub>.

CaSe + In<sub>2</sub>Se<sub>3</sub> → CaIn<sub>2</sub>Se<sub>4</sub>
