“…As shown in Figure d, with increasing BSO content ( x ), the phase structure gradually changes from R phase to R – T coexistence to T phase (i.e., from a single (200) R peak to the triple peak splitting of (002) T /(200) R /(200) T and ultimate transformation to doublet peaks of (002) T /(200) T ) . Note that the films with x = 0.05–0.10 have triple characteristic peaks, indicating that these compositions locate the MPB . BSO leads to significant distortion of the unit cells since the ionic radius of Sc 3+ is much smaller than that of Bi 3+ , which easily affects the c/a ratio and thus decreases the symmetry of the crystal …”

The enhancement of piezoelectricity without compromising the Curie temperature of a piezoelectric is challenging due to phenomenological incompatibility. In the present work, the phase diagram of (0.68-x)BiFeO 3 − xBiScO 3 −0.32PbTiO 3 , with varied addition of BiScO 3 (x = 0, 0.05, 0.10, 0.15, and 0.20), was constructed through systematic studies of the dielectric, ferroelectric, and piezoelectric properties. A rhombohedral−tetragonal phase boundary was observed near x = 0.10 BiScO 3 addition, of which the piezoelectricity was found to be seven times larger than that without BiScO 3 (∼208 pm/V vs ∼38 pm/V). Most importantly, a high Curie temperature of 430 °C is successfully inherited from binary 0.68BiFeO 3 −0.32PbTiO 3 . This is explained by optimized Bi compensation, which is observed critical regulating Curie temperature in BFO-based binary and ternary systems. These results open up a paradigm for collaboratively optimizing the Curie temperature and piezoelectric response for a number of ferroelectrics and provide a promising BiFeO 3 −BiScO 3 −PbTiO 3 film with integrated prominent performance for potential applications at elevated temperatures.

“…The traditional method is cumbersome and consumes a long time, and the non-in situ measurement method will affect the accuracy of the measurement due to the difference of d 33 values at different locations of the sample. There are still few research reports on in situ temperature-dependent d 33 measurement of piezoelectric materials until now [14][15][16].…”

Piezoelectric materials have been widely used in sensors, actuators, and transducers due to their positive and inverse piezoelectric effects, which can convert electrical and mechanical energy into one another. The most important parameter to evaluate the piezoelectric properties of materials is their piezoelectric coefficient (d33). The value of d33varies with temperature. The measurement of temperature-dependent d33is a difficult task and at present, the equipment used to measure the temperature-dependent d33 has many limitations. To overcome these limitations, the current study proposes an in-situ temperature-dependent d33measuring method based on the inverse piezoelectric effect of piezoelectric materials. The newly developed measuring equipment contains a laser vibrometer, and automatic detection program including data processing. Moreover, the image is displayed on LabVIEW program. Compared with the quasi-static temperature-dependent d33 measurement method, the KNN- based piezoelectric material demonstrated the reliability of this measurement method.

“…and B 2 represents high-valence cations (such as Nb, Sb, Ta, etc. ), are usually selected as a third component to be introduced into a BS-PT system due to their excellent dielectric and piezoelectric properties [11][12][13]. The introduction of relaxor ferroelectric end members not only improves the relaxor characteristics and electrical properties, but also can form a ternary solid solution formed with the BS-PT system, and extend its MPB region from a point to a line, which can achieve performance regulation in a wider range.…”

Piezoelectric ceramics with excellent piezoelectric properties and a high Curie temperature are important for numerous electromechanical devices in a broad range of temperature environments. In this work, the relaxor ferroelectric Pb(Yb1/2Nb1/2)O3 end member was selected to be introduced into a BiScO3-PbTiO3 high-temperature piezoelectric ceramic to reduce the dielectric loss and improve the piezoelectric properties while slightly reducing the Curie temperature. The phase structure and dielectric, ferroelectric and piezoelectric properties of 0.025Pb(Yb1/2Nb1/2)O3-(0.975−x)BiScO3-xPbTiO3 (0.60 ≤ x ≤ 0.63) ceramics were systematically analyzed, and the best electrical properties were observed in the morphotropic phase boundary region x = 0.61 with d33 = 370 pC/N, kp = 44%, Pr = 33.9 μC/cm2. Importantly, no significant depolarization was observed in the x = 0.61 ceramic from room temperature to 290 °C, demonstrating its good thermal stability and potential applications in a wide range of temperature environments.
