Abstract
Metastable ZrO2-x particles were successfully prepared by inert gas condensation (IGC) process. To control oxygen vacancies in metastable ZrO2-x, the samples were annealed between 100 and 400 °C for 2 h under low oxygen partial pressures (PO2 = 10-15 Pa). After annealing, metastable ZrO2-x samples with various oxygen vacancies (0.26<x<0.81) were successfully fabricated; also, the particle sizes were less than 10 nm.
