“…A polarization retention value beyond 75 °C is very small as compared to the P r remanent polarization at room temperature, indicating that the instability of ferroelectrics is above 75 °C. This means that ferroelectric characteristics disappeared at high temperatures and the material behaved like conventional dielectric material [ 31 , 32 , 33 ].…”

“…With increasing temperature, a decline in remnant polarization, P r , and coercive field, E c , values for niobium-substituted BNT-ST26 ceramics was observed. A polarization retention value beyond 75 • C is very small as compared to the P r remanent polarization at room temperature, indicating that the instability of ferroelectrics is above 75 • C. This means that ferroelectric characteristics disappeared at high temperatures and the material behaved like conventional dielectric material [31][32][33]. A narrower loop was seen at 50 °C and higher temperatures for ceramics with 5% Nb, suggesting the instability of ferroelectric (FE) at these temperatures, as seen in the Supplementary Figure S7.…”

Lead-free ceramics are promising candidates for replacing lead-based piezoelectric materials such as lead-zirconate-titanate (PZT) if they can compete in dielectric and ferroelectric characteristics. In this work, for lead-free piezoelectric ceramic, 0.74(Bi0.5Na0.5TiO3)-0.26(SrTiO3) (BNT-ST26) and niobium-substituted (Nb-BNT–ST26) ceramics were synthesized by solid-state reactions. The evolution of niobium substitution to the perovskite phase structure of BNT-ST26 ceramics was confirmed by X-ray diffraction (XRD) analysis and Raman spectra. Electromechanical properties of Nb-BNT-ST26 ceramics initially increased with the addition of niobium up to 0.5% and decreased with a further increase in Nb content. Temperature-dependent dielectric curves showed that the depolarization temperature (Td) decreased below room temperature because of Nb substitution. The composition with 0.5% Nb yielded a maximum bipolar strain (Smax) of 0.265% and normalized strain of d33* ~ 576 pm/V under an electric field of 4.6 kV/mm at room temperature. At this critical concentration of 0.5% Nb, maximum saturation polarization of 26 μC/cm2 was achieved. The dielectric constant with temperature peaks became more diffused and the depolarization temperature decreased with the increasing Nb content. The study concludes that Nb-doped BNT-ST26 is an excellent material for high-temperature, stable, frequency-dependent, lead-free piezoelectric devices.

Barium titanate (BaTiO3) and Bismuth ferrite (BiFeO3) have been investigated for many years. Both of them have good electrical properties in the application of industries such as flexible displays, actuators, transducers, flexible memory, multilayer ceramic capacitors, etc. Moreover, BiFeO3 is a room temperature multiferroic material that adds a halo to it. Although there are some shortcomings compared with some properties of lead-based ceramics, environmental friendly materials will be the future trend. The solid solution of BaTiO3 and BiFeO3 exactly meets this requirement. There are many reports related to it, but there are few systemic articles focused on it. So, this review recalls the progress of binary ferroelectric material: BaTiO3–BiFeO3 ceramic, especially in the field of ferroelectric, piezoelectric, energy-storage properties. Furthermore, the preparation approaches to functional ceramics are also illustrated here. Finally, we deliver a summary of this material.
