“…To visually characterize the temperature stability of the samples with the different phase structures, the sensitivity coefficient ( η ) of P r , dependent on the phase structure, was obtained according to formula 1 7

η = \frac{▵ P_{r}}{P_{r R T}} \times 100 % = \frac{P_{r T -} P_{r R T}}{P_{r R T}} \times 100 %,

where P rT is the remanent polarization at a certain temperature T, and P rRT is the remanent polarization at room temperature.…”

“…6 After the above analysis, the temperature insensitivity of hightemperature piezoelectric ceramics is the bottleneck in practical application. [7][8] Considerable efforts have been made to address temperature stability, such as phase structure regulation, MPB design, 7,9 elements replacement, 10 and ternary system construction. 11 Many reports have shown that the temperature stability of the ceramics systems with vertical phase boundaries is much better than that of the ceramic systems with other phase boundaries.…”

“…Many reports have shown that the submicron domain is beneficial for maintaining the piezoelectric properties by objecting temperature excitations to improve the temperature stability. In comparison, nano‐domains can promote a large piezoelectric activity 7,14,15 . The phase structure, which can cause lattice distortion (regarded as one of the intrinsic contributions of d 33 ), 7 is an important microstructure in ceramic systems and has a great influence on the properties of ceramics.…”

Phase structure has a strong influence on the temperature stability of ceramics; however, their influence on BiScO 3 -xPbTiO 3 has been neglected. To meet the requirements for practical applications, (0.98-x)BiScO 3 -xPbTiO 3 -0.02Bi(Sn 1/3 Nb 2/3 )O 3 (BS-xPT-BSN, 0.59 ≤ x ≤ 0.65) polycrystalline ferroelectrics with rhombohedral phase, morphotropic phase boundary (Cm and P4mm coexisting), and tetragonal phase has been prepared and studied. The relationship between the phase structures and temperature stability is established from the macro properties as well as the underlying domain behaviors. The results show that the tetragonal phase is not sensitive to temperature because of its stable domains, which is a positive motivator for improving the temperature stability of ceramics. This work provides a new strategy for the design of high-temperature piezoelectric ceramics in the future.

Acceptor doping is a common method for hardening modified piezoelectric ceramics. The mechanism through which the hardening effect can be improved has been widely studied and verified. However, the effect of defects caused by different valence states of the B‐site ions on the properties of multicomponent piezoelectric ceramics remains to be discussed. Therefore, in this work, a novel Pb(Ni1/3Nb2/3)O3–Pb(In1/2Nb1/2)O3–Pb(Mn1/3Nb1/2)–PbTiO3 quaternary hard ceramic with excellent performance is prepared and studied. The interaction between grain‐boundary defects and defect dipoles is proposed to be the mechanism behind the observed excellent performance. It is found that different types of defects improve the hardening effect in various ways. These results can provide a theoretical basis for the preparation of multicomponent piezoelectric ceramics with better properties.
