We investigated the Raman spectra of thermally reduced and untreated Y- and Ca-stabilized cubic zirconia. A substantial decrease in Raman activity was observed in the acoustic mode region upon reduction. Analyses of these spectra as a phonon density of states and of the observed spectral changes ind
A 9 mol% Y 2 O 3 -stabilized ZrO 2 specimen was annealed in boiling water for 1200 h, and the phase structure was examined by XRD and the chemical states of zirconium, yttrium and oxygen were examined by XPS. After annealing, the phase of the specimen remains entirely cubic, and the chemical states
