Abstract

Metastable ZrO2-xnano-particles were successfully prepared by the IGC process. To introduce oxygen vacancies into particles, they were annealed at temperatures between 100°C and 400°C for 2 h under low-oxygen partial pressures (Po2=10-15Pa). Therefore, ZrO2-x particles had various oxygen vacancies (0.26
