Abstract

Phase equilibria and structural transformations in the binary CeO2―Eu2O3 system at 1500 °C were studied by X-ray diffraction, petrography and electron microscopy in the overall concentration range. It was established that in the system there exist fields of solid solutions based on monoclinic (B) modification of Eu2O3, cubic (C) modification of Eu2O3 and cubic modification of CeO2 with fluorite-type structure (F). The lattice parameters of the unit cells and the boundaries of the homogeneity fields for solid solutions were determined.
