Piezoelectric actuators transform electrical energy into mechanical energy, and because of
their compactness, quick response time and accurate displacement, they are sought after in …

▪ Abstract This article reviews the defect chemistry of perovskite ferroelectric oxides such as
barium titanate and lead zirconate titanate. Such metal oxides are being considered for a …

Electrochemical reactions and ionic transport underpin the operation of a broad range of
devices and applications, from energy storage and conversion to information technologies …

Pulsed capacitors require high energy density and low loss, properties that can be realized
through selection of composition. Ceramic (Pb 0.88 La 0.08)(Zr 0.91 Ti 0.09) O 3 was found …

Extremely enhanced electrostrains (up to 0.39%) were surprisingly observed in (0.67− x) Bi
(Mg0. 5Ti0. 5) O3–xPbZrO3–0.33 PbTiO3 (BMT–xPZ–PT) ternary solid solutions, possibly …

Thanks to its small hysteresis, large electrostrictive strain in relaxor ferroelectrics is superior
than piezoelectric strain for applications in precision microactuators. Although relaxor …

A new phase boundary is revealed in (1–x)(Bi1/2Na1/2) TiO3− xBaTiO3, the most
extensively studied lead‐free piezoelectric solid solution. This discovery results from a novel …

Giant dielectric permittivity was observed in La-modified PbTiO 3 (PLT) with A-site vacancy.
The observed values of PLT with A-site vacancy are 1 order of magnitude larger than those …

Electromechanical and dielectric properties of (1–3x) NBT–2x KBT–xBT lead-free ceramics
were investigated. XRD results show that the crystalline structure of the ceramics was …

The structure and properties of Mn‐doped 0.67 BiFeO3‐0.33 BaTiO3 ceramics are
systematically investigated with respect to the effects of annealing prior to rapid cooling by …
