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 Ce₂O_3.4TiO₂ have been measured. The solubility of TiO_2-m in Ce₂O₃.3TiO_2-m (m≈0.11) was determined and the resulting solutions were investigated; the results indicate that an additional 2.5 TiO_2-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.
