The analysis of the Raman spectra leads to the determination of the monoclinic phase extension at different temperatures in a very good agreement with those determined by diffraction techniques. Therefore the obtained results show that Raman spectroscopy is a powerful and suitable technique to study structural phase transitions in PbZr 1-xTixO3. © 2002 Taylor & Francis.21-26engPhase transitionsPZTRaman spectroscopyDiffractionLeadMorphologyThermal effectsTitaniumZirconiumDiffraction techniquesMorphotropic phase boundaryPhase boundary regionFerroelectric ceramicsArtigo10.1080/00150190211602WOS:000177216900005Acesso restrito2-s2.0-337462848406725982228402054
