Large Electrocaloric Effect in Stretched Relaxor Ferroelectric Polymers near Morphotropic Phase Boundary

open access: yesChemistry
Use of the morphotropic phase boundary (MPB) is a promising approach to enhance the electrocaloric effect in ferroelectric polymers. This is usually achieved by a composition method, and polymer processing near the MPB to tune electrocaloric response has

The Properties of Pbzts Ceramics Near Orthorhombic-Rhombohedral Morphotropic Phase Boundary

open access: yesArchives of Metallurgy and Materials, 2011
We present the results of obtaining and investigations of (Pb1􀀀xBax)((Zr1􀀀yTiy)1􀀀zSnz)O3 (PBZTS) ceramics with x=const=0.2, y=const=0.08, z=0, 0.02, 0.04, 0.06 and 0.08. Ceramic samples have been obtained by conventional ceramic technology from oxides PbO, ZrO2, TiO2, SnO2 and barium carbonate BaCO3.

Ultrahigh thermal stability and piezoelectricity of lead-free KNN-based texture piezoceramics

open access: yesNature Communications
The contradiction between high piezoelectricity and uniquely poor temperature stability generated by polymorphic phase boundary is a huge obstacle to high-performance (K, Na)NbO3 -based ceramics entering the application market as Pb-based substitutes. We

Contribution to the study of the coexistence of phases tetragonal-rhombohedral in ceramic type PZT and general form: Pb [ZrxTi0,95-x(Mo1/3In2/3)0.05]O3

open access: yesEPJ Web of Conferences, 2012
Pb[ZrxTi0,95-x(Mo1/3In2/3)0.05]O3 piezoelectric ceramics with varying Zr/Ti ratio were prepared by the conventional method of thermal synthesis of mixed-oxides.the samples structures was determined by X-ray diffractometry to demonstrate the co-existence ...

Composition-Dependent Dielectric Properties of Poly(vinylidene fluoride-trifluoroethylene)s Near the Morphotropic Phase Boundary

open access: yes, 2019
The discovery of relaxor behavior in poly­(vinylidene fluoride-trifluoroethylene) [P­(VDF-TrFE)] copolymers plays a crucial role in driving the formation of a morphotropic phase boundary (MPB) near which large enhancements of dielectric and piezoelectric

Exploring the morphotropic phase boundary in copper(II)-modified Pb[Zr0.54Ti0.46]O3 ferroelectrics

open access: yes, 2005
Copper(II)-doped Pb[Zr0.54Ti0.46]O3 (PZT) ferroelectrics with a dopant concentration of 0.25 molthinsp% were investigated at high magnetic fields, enabling an enhanced resolution of the structural distortion at the dopant site.

Rhombohedral-Orthorhombic Morphotropic Phase Boundary in BiFeO3-based Multiferroics: First-Principles Prediction

open access: yes, 2012
A pseudo-binary solid solution formed with two structurally dissimilar end members possesses a structural phase boundary, commonly called the morphotropic phase boundary (MPB). Many of the technologically useful piezoelectric oxides exhibit their maximum
