Piezoelectric Ceramics with Compositions at the Morphotropic Phase Boundary in the BiFeO3–PbZrO3–PbTiO3 Ternary System
Since ceramics in the PbZrO3–PbTiO3 binary system display excellent piezoelectric properties and those in BiFeO3–PbTiO3 exhibit high Curie temperatures, morphotropic phase boundary (MPB) compositions in the BiFeO3–PbZrO3–PbTiO3 ternary solid solution system are investigated for the development of piezoelectric ceramics for high temperature applications. It is found that the MPB compositions in ...
متن کاملDielectric and piezoelectric properties of sodium lithium niobate Na1−xLixNbO3 lead free ferroelectric ceramics
High density sodium lithium niobate lead free ceramics near the morphtropic phase boundary [NaxLi1−xNbO3, (LNN), x=0.12] were prepared by the solid state reaction method. XRD patterns showed that the lattice structures were changed after polarization. The temperature dependence of the dielectric constant and dielectric loss, pyroelectric coefficient and DSC curves of LNN ceramics showed that th...

xBaZrO3-(1!x)BaTiO3 solid solutions (x 1⁄4 0, 0.04, 0.06, 0.08, 0.12, and 0.18) synthesized via conventional solid state reaction method exhibit piezoelectric coefficients comparable to those of “hard” PZT-8, PZT-4, and even “soft” PZT-5A. Doping also improves the poling efficiency of xBaZrO3-(1!x)BaTiO3 ceramics. Study of temperature dependence of the dielectric and piezoelectric properties re...
متن کاملRecent Progress on BaTiO3-Based Piezoelectric Ceramics for Actuator Applications
Due to issues with Pb toxicity, there is an urgent need for high performance Pb-free alternatives to Pb-based piezoelectric ceramics. Although pure BaTiO3 material exhibits fairly low piezoelectric coefficients, further designing of such a material system greatly enhances the piezoelectric response by means of domain engineering, defects engineering, as well as phase boundary engineering. Espec...
