Interaction of lantanum and gadolinium oxides at temperature 1100 °C

Abstract

Phase equilibria and structural transformations in the binary La₂O₃—Gd₂O₃ system at 1100 °C were studied by X-ray diffraction in the overall concentration range. It was established that in the system there exist fields of solid solutions based on hexagonal (A) modification of La₂O₃ and monoclinic (B) and cubic (C) modification of Gd₂O₃ . The lattice parameters of the unit cells and the boundaries of the homogeneity fields for solid solutions were determined
