Phase equilibriums and structure transformations in the CeO₂–Er₂O₃ system have been studied within 1500–600 °C in the full concentration range using XRD and petrography methods. It was established that the system is characterized by the formation of solid solutions on the basis of cubic modification of Er₂O₃ (C-type) and fluorite CeO₂ (F-type). Solubility limits and concentration dependences of lattice parameters were determined for the phases forming in the system.
