Neptunium nitride is a binary inorganic compound of neptunium and nitrogen with the chemical formula NpN.[1][2]
Preparation
Neptunium nitride can be prepared by the reaction of freshly obtained neptunium hydride and ammonia:[3]
- NpH
3 + NH
3 → NpN + 3H
2
The reaction of neptunium and nitrogen can also obtain neptunium nitride:
- 2Np + N
2 → 2NpN
Physical properties
Neptunium nitride forms black crystals in the cubic system with Fm3m space group.[4][5] It is insoluble in water[6] and decomposes if heated.[7]
- 2NpN → 2Np + N
2
Uses
Neptunium nitride is used as a target material for plutonium-238 production.[8]
- 23793Np + n → 23893Np
