The authors study the interaction with nitrogen of uranium amalgam with a metal content of 600-1000 mg/ml Hg in the temperature range of 350-800 degrees C. They establish that the principle product of the interaction is nonstoichiothermic uranium nitride UN (X = 1.5-1.8). Preliminary washing with dimethylsulfoxide and acetonitrile allows the content of uranium dioxide obtained to be reduced to 3-4 mole %. The authors hypothesize that in the interaction with nitrogen not only metallic uranium dissolved in the mercury takes part, but also thermally unstable intermetallic compounds of the composition UHg /SUB x/ (x = 1-4). An increase in the temperature up to 800 degrees together with a reduction of the partial pressure of the nitrogen to 70 torr does not lead to the formation of stoichiothermic uranium mononitride.
