The aim of this investigation is to study the defect reactions and the associated thermodynamic behavior of calcium doped cerium dioxide as a function of nonstoichiometry. These defect reactions, involve the formation of oxygen vacancies, electrons, and holes which determine the nonstoichiometry, x, of the material as a function of temperature and oxygen partial pressure, Po2...
