Synthesis

edit

CeN can be obtained by direct chemistry of cerium with nitrogen at 850–900 °C.[3][4]

2Ce + N2 → 2CeN

Physical properties

edit

CeN forms a brown powder with a melting point of 2557 °C. The compound is a semi-metallic conductor, stable in dry air.[3]

Uses

edit

CeN can be used to simulate the properties of uranium mononitride (UN).[5]
