Abstract

The electrical conductivity of sintered specimens of was measured over the temperature range 800°‐1500°C and from 1 to 10 −21 atm of oxygen. Based on the agreement between these experimental data and theoretically derived relations obtained using the law of mass action, the nonstoichiometric defect structure of was interpreted in terms of a defect structure consisting of triply and quadruply ionized cerium interstitials and localized electrons. The standard enthalpies of formation for the following defect reactions in were determined
