Ferroelectric and Piezoelectric Properties of Lead-Free BCT-<i>x</i>BZT Solid Solutions

Abstract

Lead-free BCT-xBZT solid solutions were prepared by the conventional solid-state reaction route. A full set of elastic, piezoelectric, and dielectric parameters were measured using a resonance method and calculated following the formulae in the IEEE standard for piezoelectric ceramics. In addition, ferroelectric properties were also investigated to demonstrate the “softening” and the diffuse transitions in the material.
