Enhanced dielectric and piezoelectric properties of xBaZrO3-(12x)BaTiO3 ceramics
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 کاملPiezoelectric and electrostrictive strain behavior of Ce-doped BaTiO3 ceramics
The ferroelectric and strain behavior of the Ba(Ti12yCey)O3 solid solutions was studied. Three phase transition temperatures were shifted with increasing Ce concentration, and pinched at y 50.06. The samples could be structurally indexed by x-ray diffraction in a tetragonal symmetry at y<0.06; and in a pseudo-cubic symmetry at y.0.06. The strain levels in the range of 0.15–0.19% at ;60 kV/cm wi...
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...
متن کاملUnfolding grain size effects in barium titanate ferroelectric ceramics
Grain size effects on the physical properties of polycrystalline ferroelectrics have been extensively studied for decades; however there are still major controversies regarding the dependence of the piezoelectric and ferroelectric properties on the grain size. Dense BaTiO3 ceramics with different grain sizes were fabricated by either conventional sintering or spark plasma sintering using micro-...
متن کاملFerroelectric Domain Structure and Local Piezoelectric Properties of Lead-Free (Ka0.5Na0.5)NbO3 and BiFeO3-Based Piezoelectric Ceramics
Recent advances in the development of novel methods for the local characterization of ferroelectric domains open up new opportunities not only to image, but also to control and to create desired domain configurations (domain engineering). The morphotropic and polymorphic phase boundaries that are frequently used to increase the electromechanical and dielectric performance of ferroelectric ceram...
