Phase formation investigation in PZT materials by Synchrotron X-ray absorption spectroscopy techniques

Abstract

© 2017 Taylor & Francis Group, LLC. PbZr1-xTixO3(PZT) powders (x = 0.45–0.54) were synthesized by conventional solid state reaction method. The phase information was investigated by a combination of X-ray diffraction and X-ray absorption spectroscopy (XAS) techniques. The XRD measurements indicated the global phase formation of the prepared powders was the mixture of rhombohedral and tetragonal phases. However, the local phase formation around titanium atom was revealed using X-ray Absorption Near-Edge Structure (XANES), indicating the existence of monoclinic phase within the compositional range studied.
