Abstract

In this work we present a Raman study of PbZr 1-x Ti x O 3 ceramics with composition values close to the morphotropic phase boundary region. 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-x Ti x O 3 . [ABSTRACT FROM AUTHOR]
