Piezo‐Spectroscopic Coefficients of Tetragonal‐Prime Yttria‐Stabilized Zirconia

The Raman piezo-spectroscopic constants of tetragonal prime yttria-stabilized zirconia under uniaxial compression have been determined. Although the Raman band at 461 cm -1 is not the most intense, it is the most appropriate peak for stress measurement because of its large stress-induced peak shift and the minimum overlap with the other Raman peaks. The peak separation between bands at 258 and 461 cm -1 or 258 and 638 cm -1 can also be used to measure stress.
