Quantitative phase analysis in tetragonal-rich tetragonal/monoclinic two phase zirconia by Raman spectroscopy

摘要

Quantitative phase analysis in the tetragonal-rich tetragonal/monoclinic two-phase zirconia has prac-tical importance in the study of stress-induced phase transformations in tetragonal zirconia polycrystals (TZP) or partially stabilized zirconia (PSZ). Using an X-ray diffraction (XRD) technique, such a quantitative phase analysis can be accomplished from the calibration curves proposed by Evans et cd. [1] or Toraya et cd. [2], although information on the spatial distribution of the monoclinic phase is not available.
