Chemical compound
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
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]
