Study of global and local crystallography at the domain boundaries of lead zirconate titanate piezoelectric ceramics

Abstract

Reliable automated orientation mapping of 90°domains in a tetragonal perovskite has been achieved for the first time using both EBSD and TEM-Kikuchi pattern analysis. This has been used to compare local measurements of c/a ratios in PZT with global measurements by X-ray diffraction. The local c/a rations are in broad agreement with the global measurements, but further work is needed to determine whether the small discrepancies are real local variations or are caused by experimental factors. © 2008 IOP Publishing Ltd.
