Popis: Using nanoparticles of CeO2 and ZrO2 prepared by a chemical precipitation method as starting materials, single-phase cubic Ce0.5Zr0.5O2 solid solution (c-Ce0.5Zr0.5O2) has been synthesized under 3.1 GPa at 1073 K for the first time. The EPR and XPS measurements show that there exists no Ce3+, in it and that the Ce4+ has not been reduced to Ce3+ after annealing. The transport mechanism is ionic for the c-Ce0.5Zr0.5O2. The bulk conductivity is the same as that of CeO2, but smaller than that of Y2O3-stabilized ZrO2. (Some figures in this article are in colour only in the electronic version).
