Abstract

This investigation highlights the influence of isovalent Sr2+ on acceptor Fe3+ modified PLZT for microstructure and its effect on dielectric and piezoelectric properties [Pb0.985−yLa0.015Sry][(Zr0.538Ti0.462)0.985Fe0.015]O3 where y = 0, 0.5, 1.0, and 1.5 mol% nanocrystalline solid solutions near morphotrophic phase boundary were synthesized by solid state reaction method. X-ray diffraction patterns indicated that Sr increment resulted in strong tetragonality. Grain size and apparent density enhanced up to y = 1.5 mol%. TEM studies indicated that average particle size ranged from 23 to 68 nm. PLSZFT compositions attained optimum εRT, d33, and kp at y = 1.5 mol%, respectively which could be suitable for possible piezoelectric applications. The influence of grain size on dielectric and piezoelectric properties are reported.
