Abstract
The solubility of Ce2Ti2O7 in Ln2Ti2O7 (LnGd, Er and Lu) was determined experimentally. It was found that the solubility increases as the ionic radius of the host lanthanide element decreases. The lattice parameters of Ce2O3.4TiO2 have been measured. The solubility of TiO2-m in Ce2O3.3TiO2-m (m≈0.11) was determined and the resulting solutions were investigated; the results indicate that an additional 2.5 TiO2-m can be dissolved without significantly changing the lattice parameters. Limits for the solubility of Ce4+ in compounds such as Ce2O3.nTiO2 in which n=2 or 4 were also estimated.
