Phase equilibriums in the Dy2O3-MoO2 system are investigated by the methods of X-ray phase analysis, DTA, and IR spectroscopy. Molybdates(IV) of composition Dy2Mo2O7-x and Dy2MoO5-y occur in the system. In addition, in the range of concentrations from 5 to 25 mol % Dy2O3 the phase X is formed, which coexists with MoO2 and Dy2Mo2O7. The lattice parameters of the revealed phases are calculated.
