dc.description.abstractPolycrystalline samples of Pb[(1 - x)(Zr<inf>1/2</inf>Ti<inf>1/2</inf>) - x(Zn<inf>1/3</inf>Ta<inf>2/3</inf>)]O <inf>3</inf> , where x = 0.1-0.5 were prepared by the columbite and wolframite methods. The crystal structure, microstructure, and dielectric properties of the sintered ceramics were investigated as a function of composition via X-ray diffraction (XRD), scanning electron microscopy (SEM), and dielectric spectroscopy. The results indicated that the presence of Pb(Zn<inf>1/3</inf>Ta<inf>2/3</inf>)O<inf>3</inf> (PZnTa) in the solid solution decreased the structural stability of overall perovskite phase. A transition from tetragonal to pseudo-cubic symmetry was observed as the PZnTa content increased and a co-existence of tetragonal and pseudo-cubic phases was observed at a composition close to x = 0.1. Examination of the dielectric spectra indicated that PZT-PZnTa exhibited an extremely high relative permittivity at the MPB composition. The permittivity showed a ferroelectric to paraelectric phase transition at 330 °C with a maximum value of 19,600 at 100 Hz at the MPB composition. © 2008 Springer Science+Business Media, LLC.
