摘要：

A CeO1.5-CeO2-CeF3 section of the ternary Ce-O-F system has been studied under an argon atmosphere. It was found that CeO2 is less than 0.03 oxygen deficient. In addition, fluorine substitutes for oxygen to form a CeO2-yFx solid solution up to x = 0.07. The dopant effect of fluorine on the electrical conductivity of CeO2 has been established, in addition to the energies of activation for the charge-carrier mobility. A phase stability diagram of the fluorine-doped CeO2 is presented. © 1990.
