Abstract
A simplified analytical treatment of rather complex defect equilibria involving systems with multivalent dopants is presented. This approach is first demonstrated for the case of Gd2Ti2O7; doped with multiple valent donors, in which the effects of variations in donor ionization levels and in the equilibrium constants on the defect equilibria are examined. The conductivity data of U doped CeO2 are then evaluated, leading to equilibrium constants in good agreement with previous results, but allowing a more complete analysis.
