“…When x = 0.61, the material is in a two-phase coexistence state-that is, there is a morphotropic phase boundary region, which is beneficial for obtaining high dielectric and piezoelectric properties. This is different from the MPB region of the pure (1−x)BS-xPT system located at x = 0.64, due to the introduction of Yb 3+ and Nb 5+ cations in the PYN system which replace the Sc 3+ and Ti 4+ ions, resulting in a slight shift in the MPB region [29]. With the increase in PT content, the (200) peak gradually widens and splits, and completely splits into two diffraction peaks (002)/(200) in the x = 0.62 ceramic, indicating that the phase structure of the PYN-BS-xPT ceramic shifted from an R phase to a T phase [28].…”

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.
