“…The d 33 * ≈ 520 and 550 pm V −1 at 25 °C increased to 570 and 610 pm V −1 at 125 °C for BFBNdT, and BFBSmT ceramics, respectively. It was noticed that only a 10% variation occurred in the d 33 * values in the temperature 25-125 °C of BFBNdT and BFBSmT ceramics, which is far lower than the other reported BFBT [24,[31][32][33][34][35][36][37][38] and KNN-based [39][40][41][42][43][44][45] ceramics as shown in Figure 9g.

In piezoceramics, the Curie temperature (TC) and piezoelectric coefficient (d33) are often inversely proportional, so it is very difficult to optimize high piezoelectricity and TC simultaneously. In addition, the high and temperature‐insensitive piezoelectric strain coefficient (d33*) with small hysteresis is also a longstanding obstacle in the development of lead‐free ceramics. In this work, a facile approach of donor doping strategy is adopted to replace Ba2+ with Yb3+, Y3+, Sm3+, and Nd3+ as a result, a high TC of 450 °C and outstanding d33 of 422–436 pC N−1 is achieved by a novel magnetic poling method. Thermally‐stable and outstanding piezoelectric strain performance (d33* ≈ 520–550 pm V−1 and ΔST ≈ 10%) with small strain hysteresis (H < 20%) results are highly encourageable in lead‐free ceramics. The main factors contributing to high piezoelectricity are the morphotropic phase boundary, suppression of defect charges by donor doping, thermal quenching, mesoscale nanodomain size, and novel poling method. The excellent piezoelectric performance and high TC of this work are superior to those of state‐of‐the‐art piezoceramics. The synergistic approaches of compositional design strategy and novel poling process in this work are highly beneficial for temperature‐insensitive piezoelectric sensor and actuator applications.

“…Dielectric capacitors exhibiting ultrafast charge/discharge speed, high temperature stability, good fatigue endurance, and high power density (up to 108 W/kg) have attracted extensive attention in the community of energy storage. − In comparison with electrical energy storage, for example, batteries and supercapacitors, dielectric energy storage has unique advantages for applications in pulsed power systems. An emergent topic in this field is to develop environmentally benign ceramics to replace market-dominating lead zirconate titanate (Pb(Zr,Ti)O 3 , PZT) .…”

Incorporation of polymorphic ferroelectric nanodomains into a paraelectric matrix has been proven to be effective to achieve high energy storage density in a relaxor ferroelectric system. In this work, we fabricated short-range ordered polymorphic 0.20BiFeO3–(0.80 – x)BaTiO3 nanodomains in a paraelectric xSrTiO3 host (0.40 ≤ x ≤ 0.65) to form ternary relaxors with transition temperatures in the range of 425–460 °C. The addition of SrTiO3 suppresses the P–E loops of the binary BiFeO3–BaTiO3 system and improves the recoverable energy and energy storage efficiency. A well-sintered solid solution exhibits nearly ideal relaxor ferroelectric behavior for x = 0.50, which demonstrates the highest tetrahedral c/a ratio (1.0042), saturation polarization (26.39 μC/cm2), breakdown strength (183.1 kV/cm), and recoverable energy (2.15 J/cm3 at 190 kV/cm) and also shows high current density, high power density, and short discharge time. The overall evolution of the c/a ratio, saturation polarization, and recoverable energy follows an x-dependent volcanic shape, while the variation of residual polarization is x-independent. The maximum energy storage efficiency of 95.56% is observed for x = 0.55 at 200 kV/cm. These findings suggested that the 0.20BiFeO3–(0.80 – x)BaTiO3–xSrTiO3 system is promising for dielectric energy storage applications.

“…It has been shown by many researchers that the use of quenching procedures is an effective way to transform the slim ferroelectric polarization‐electric field (P‐E) loops in BiFeO 3 ceramics into a more open, well‐saturated form 19 and consequently it is possible to obtain remarkable functional properties by this means 20–25 . For the composition 0.8BF‐0.2BT, it was shown that annealing at 800°C for 20 h followed by water‐quenching or furnace‐cooling can reduce the coercive field and enhance the ferroelectricity; these effects were attributed to higher rhombohedral distortion, relaxation of lattice strains associated with the A‐O bond length, and redistribution of dipolar defects 26 .…”

The structure and properties of Mn‐doped 0.67BiFeO3‐0.33BaTiO3 ceramics are systematically investigated with respect to the effects of annealing prior to rapid cooling by quenching in air. Air‐quenching induces a change in crystal structure from pseudo‐cubic to rhombohedral, with higher quenching temperatures leading to an increased rhombohedral distortion. These structural changes are correlated with the appearance of more well‐defined ferroelectric domain configurations. It is shown that the surface preparation procedures for XRD measurements can induce significant changes in the peak profiles, indicating differences in crystal structure between the surface and bulk regions. Frequency dispersion in the temperature‐dependent relative permittivity for the as‐sintered sample is significantly reduced after quenching, accompanied by enhancement of the Curie point and improved temperature‐stability of piezoelectric properties. It is proposed that the formation of defect clusters by A‐site cation diffusion during cooling is circumvented by quenching, leading to the observed modification of structural distortion and ferroelectric properties.
