Gas-solid reactions of UO2SO4 with H2, H2S and CS2 to form uranium (IV) oxysulfide, UOS, as a single phase were studied on the basis of thermodynamical analysis of these reactions. H2S was proved to be the best reaction agent. The reaction of UO2SO4 with CS2 resulted in the formation of UOS and US2 mixtures. A refinement of the crystal structure of UOS was made giving isotropic temperature factors and a smallest R value of 1.71%. The obtained UOS showed a p-type semi-conductivity with activation energy 67.5 meV.
