Preparation and properties Calcium selenide can be prepared via the reaction of calcium and H₂Se in liquid NH₃.Kohle, J.; Petzel, T.

Ca + H₂Se → CaSe + H₂

Calcium selenide reacts with indium(III) selenide in vacuum at high temperature to give CaIn₂Se₄.Yagubov, N. I.; Guliev, T. N.; Rustamov, P. G.; Chiragov, M. I.; Safarov, V. G.
