Neptunium nitride is a binary inorganic compound of neptunium and nitrogen with the chemical formula NpN. [1] [2]
Neptunium nitride can be prepared by the reaction of freshly obtained neptunium hydride and ammonia: [3]
The reaction of neptunium and nitrogen can also obtain neptunium nitride:
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]
Neptunium nitride is used as a target material for plutonium-238 production. [8]
