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 ziraconia 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 Contents 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 teteragonal zirconia solid solutions.
