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

Contents

Synthesis

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

2Ce + N2 → 2CeN

Physical properties

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

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