Cerium nitride is a binary inorganic compound of cerium and nitrogen with the chemical formula CeN.^[1]^[2]

Synthesis

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

2Ce + N₂ → 2CeN

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

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