Abstract

Using nanoparticles of CeO₂ and ZrO₂ prepared by a chemical precipitation method as starting materials, single-phase cubic Ce_0.5Zr_0.5O₂ solid solution (c-Ce_0.5Zr_0.5O₂) 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-Ce_0.5Zr_0.5O₂. The bulk conductivity is the same as that of CeO₂, but smaller than that of Y₂O₃-stabilized ZrO₂.
