Preparation

Cerium monoselenide can be obtained by reducing cerium selenide with metallic sodium at 600 °C (or calcium at 1000 °C):[2]

Ce2Se3 + 2Na → 2CeSe + Na2Se

The reduction of cerium selenide by cerium dihydride can also produce cerium monoselenide:[1]

Ce2Se3 + CeH2 → 3 CeSe + H2

Properties

Like many other rare earth monochalcogenides, Cerium monoselenide has metallic-type electrical conductivity and a NaCl-type crystal structure.[3]
