Abstract

The study of the process of interaction between nitrogen and
nearly stoichiometric uranium monosulphide reveals at least three
distinct stages. The first one (200-580° C) is characterized by limited
interstitial dissolution of nitrogen in th e lattice. At approximately
580° C , US starts to react with N 2 yielding uranium sulphonitride
of the composition U 2S 2Ny. Above 1200° C U2S 2N y decomposes into
US and U 2S2 _ xNy. The X-ray powder diffraction m ethod was used
in order to derive the most probable atomic positions in the crystal
structure of U2S2N.
