Year: 2017
Type: article
Abstract: The phase equilibria in the binary system Nd2O3−Y2O3 at 1500 °C were studied in the overall concentration range by means of X-ray analysis and petrography. The samples of various compositions were derived from nitrate acid solutions (prepared by dissolving neodymia and yttria powders in hot diluted nitric acid) by evaporation, drying and heat treatment at 1100 and 1500 °C. Solid solutions based on different crystalline modifications of the components were obtained. The boundaries of solubility and concentration dependence of the lattice parameters for the phases formed in the system were defined.
