摘要：

Raman spectra of tetragonal zirconia were studied for the systems ZrO2-Y2O3, ZrO2-CeO2, ZrO2-Y2O3-Nb2O5, and ZrO2-Y2O3-Ta2O5. There was no change in the Raman bands for tetragonal zirconia in the ZrO2-Y2O3 system as a function of Y2O3 content. On the other hand, in the ternary systems, the Raman lines corresponding to the stretching modes of two sets of cation-oxygen bonds shifted to greater wave numbers as either Nb2O5 or Ta2O5 content increased in Y2O3-stabilized tetragonal zirconia. This difference was interpreted by local bonding environments of the pentavalent cations, which were supposed to occupy tetrahedral sites in tetragonal zirconia solid solutions.
