“…The main difference could be presented as the fact that Hume-Rothery rules are based on valency and electronegativity similarities [78,79] between two comparable entities : solute and solvent atoms, while the Lattice Compatibility Theory LCT focuses rather on lattice parameters similarities between a privileged structure: the host matrix and that of a less important entity: the doping agent.…”

“…BaTiO 3 is a perovskite ferroelectric which has paraelectric-ferroelectric phase transition at 120°C [13]. Some other authors reported that complex electronic systems, such as BaZr 0.025 Ti 0.975 O 3 -BiFeO 3 , BiFeO 3 -NaNbO 3 , BiFeO 3 -BaTiO 3 , etc., have extensively been studied to make BFO a reliable base for the fabrication of useful devices [14,15].…”

In the present paper, the ternary system 0.90 BaTiO 3-0.07 BiFeO 3-0.03 CaSnO 3 (referred as BTO-BFO-CSO-3) near the morphotropic phase boundary (MPB) was synthesized via a cost effective mixed-oxide route and sintered at 1050°C. Phase composition analysis confirms that the sample crystallizes in orthorhombic phase with few impurity peaks. Room temperature Raman spectrum depicts the phonon peaks characteristic for BTO-BFO-CSO-3 structure. Microstructural examination by scanning electron microscope shows the uniform distribution of grains on the surface of the density sample. The capacitive and resistive properties at different frequencies and temperatures were obtained by modulus and impedance spectroscopy. The non-Debye relaxation mechanism is highlighted by the impedance analysis. The electrical properties associated with the impedance of the prepared sample are found to be dependent on temperature and frequency. The transport properties follow the Arrhenius equation and the activation energy is calculated for the sample.

“…As well‐known, Zr is usually used to modify the piezoelectric properties of BaTiO 3 ‐based materials . In addition, it is found that Zr doping is an effective way to modify the dielectric and ferroelectric properties of BiFeO 3 –BaTiO 3 solid solutions . Thus, in this article, Zr was introduced to substitute a part of Ti in the BF–BT solid solutions, and their electric field‐induced strain, temperature‐dependent dielectric, and piezoelectric properties were investigated systematically.…”

0.75BiFeO 3 -0.25Ba(Zr x Ti 1 -x ) + 0.6 wt% MnO 2 (0.75BF-0.25BZT) ceramics with Mn addition were prepared by the solid-state reaction method. The high-field strain and high-temperature piezoelectric properties of 0.75BF-0.25BZT ceramics were studied. Introduction of Zr in the solid solutions decreased the Curie temperature slightly, and improved the dielectric and piezoelectric properties obviously. The piezoelectric properties of 0.75BZT-0.25BT ceramics reached the maximum at Zr content of 10 mol%. The Curie temperature T c , dielectric constant e and loss tand (1 kHz), piezoelectric constant d 33 , and planner electromechanical coupling factor k p of 0.75BF-0.25BZT ceramics with 10 mol% Zr were 456°C, 650, 5%, 138 pC/N, and 0.30, respectively. The high-field bipolar and unipolar strain under an electric field of 100 kV/cm reached up to 0.55% and 0.265%, respectively, which were comparable to those of BiScO 3 -PbTiO 3 and "soft" PZT-based ceramics. The typical "butterfly"-shaped bipolar strain and frequency-dependent peak-to-peak strain indicated that the large high-field-induced strain may be due to non-180°domain switching. Rayleigh analysis reflected that the improved piezoelectric properties resulted from the enhanced extrinsic contribution by Zr doping. The unipolar strain of 0.75BF-0.25BZT ceramics with 10 mol% Zr was almost linear from RT to 200°C. These results indicated that 0.75BF-0.25BZT ceramics were promising candidates for high-temperature and lead-free piezoelectric actuators.
