Large Piezoelectric Effect in Pb-Free Ceramics
TL;DR: It is predicted that the single-crystal form of the MPB composition of the present system may reach a giant d(33) = 1500-2000 pC/N, which may provide a new recipe for designing highly piezoelectric materials (both Pb-free and P b-containing) by searching MPBs starting from a TCP.
Journal ArticleDOI
Microstructure basis for strong piezoelectricity in Pb-free Ba(Zr0.2Ti0.8)O3-(Ba0.7Ca0.3)TiO3 ceramics
Jinghui Gao,Dezhen Xue,Yu Wang,Dong Wang,Lixue Zhang,Haijun Wu,Shengwu Guo,Huixin Bao,Chao Zhou,Wenfeng Liu,Sen Hou,Ge Xiao,Xiaobing Ren +12 more
TL;DR: In this paper, the authors used transmission electron microscopy to study the microstructure feature of Pb-free piezoceramic Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 across its piezoelectricity-optimal morphotropic phase boundary (MPB) by varying composition and temperature, respectively.
Journal ArticleDOI
Triple-point-type morphotropic phase boundary based large piezoelectric Pb-free material—Ba(Ti0.8Hf0.2)O3-(Ba0.7Ca0.3)TiO3
TL;DR: In this article, a triple-point morphotropic phase boundary (TMPB) based Pb-free system with anomalous ac (dielectric and piezoelectric) and dc (P-E hysteresis) properties is presented.
Journal ArticleDOI
Ultrahigh enhancement rate of the energy density of flexible polymer nanocomposites using core–shell BaTiO3@MgO structures as the filler
Peng-Jian Wang,Di Zhou,Huan-Huan Guo,Wenfeng Liu,Jinzhan Su,Mao Sen Fu,Charanjeet Singh,Sergei V. Trukhanov,Sergei V. Trukhanov,Alex Trukhanov,Alex Trukhanov +10 more
TL;DR: In this paper, a core-shell BaTiO3@MgO (BT@MO) nanostructure was fabricated, in which highly insulating MgO was directly coated on a continuous ferroelectric nanoparticle BaO3 shell through a chemical precipitation method to improve the breakdown strength and electric displacement under high electric field.
Journal ArticleDOI
Recent Progress on BaTiO3-Based Piezoelectric Ceramics for Actuator Applications
TL;DR: In this paper, the authors summarize the idea of designing high property BaTiO3 piezoceramic through domain engineering, defect-doping, as well as morphotropic phase boundary (MPB).
