Phase equilibria in the Dy2O3-[Mo2O5] system are investigated by methods of physicochemical analysis. Molybdates of different composition containing molybdenum in the +6, +5 and +4 oxidation states are found, and the regions of their occurrence are determined. The phase composition and structure of forming molybdates are shown to depend on the annealing conditions.
