Interaction of the ceria with europia at temperature 600 °C

Abstract

Phase equilibria and structural transformations in the binary CeO₂―Eu₂O₃ system at 600 °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 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.
