The Na and Ce co-doped CaBi4Ti4O15 (CBT) Aurivillius ceramics in a Ca1-x(Na0.5Ce0.5)xBi4Ti4O15 (CNCBT, x = 0, 0.03, 0.05, 0.08 and 0.12) system were synthesized by the conventional solid-state sintering method.All compositions show a single-phase orthorhombic (space group A21am) structure at room temperature. The shift of the Curie point Tc towards lower temperatures on doping results from the increased tolerance factor t.The substitution-enhanced ferroelectric performance with large maximum polarization and facilitated domain switching is evidenced by the developed P-E and I-E hysteresis loops. The piezoelectric coefficient d33 (20.5 ± 0.1 pC/N) of the x = 0.12 sample is about four times larger than that of pure CBT. The improved piezoelectric properties can be attributed to the high remnant polarization and relatively high permittivity. In addition, multisized (micron and sub-micron) domain structures were observed in the CNCBT ceramics by piezoelectric response microscopy. The multiple sized ferroelectric domain structure with smaller domains is beneficial to the easy domain switching, enhanced ferroelectric performance and improved piezoelectric properties of the CNCBT ceramics. The designed Aurivillius-phase ferroelectric ceramics with the Curie point around 765 °C and high d33 are suitable for high-temperature piezoelectric applications.

“…The existence of oxygen vacancies can be possibly due to the reduction of Ti 4+ cations during the sintering, which is common in piezoelectric ceramics prepared by the solid-state sintering method. The underlying mechanism can be described by the Kröger-Vink notation, as reported in other perovskite ferroelectric ceramics [29].…”

“…An increase in the electric field strength causes gradual macroscopic polarisation, as demonstrated in Figure 1 a. The dramatic polarization change near E c is primarily due to polarization reversal (domain flipping), but at the high-field end, the polarization is saturated and the material behaves as a linear dielectric [ 6 , 34 ]. There is a back-switch in some domains as the electric field intensity decreases, but at zero field the network polarization is non-zero, resulting in remnant polarization ( P r ).…”

Ferroelectric materials are known to possess multicatalytic abilities that are nowadays utilized for removing organic pollutants from water via piezocatalysis, photocatalysis, piezo-photocatalysis, and pyrocatalysis processes. The Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZTO) ceramic is one such ferroelectric composition that has been extensively studied for electrical and electronic applications. Furthermore, the BCZTO ceramic has also shown remarkable multicatalytic performance in water-cleaning applications. The present review explores the potentiality of BCZTO for water-cleaning and bacterial-killing applications. It also highlights the fundamentals of ferroelectric ceramics, the importance of electric poling, and the principles underlying piezocatalysis, photocatalysis, and pyrocatalysis processes in addition to the multicatalytic capability of ferroelectric BCZTO ceramic.

“…Furthermore, the discovery of a low-symmetry monoclinic phase in close proximity to the MPB has added a new dimension to the understanding of high properties. [9][10][11][12] This monoclinic phase's polarization lies in the (110) PC plane, serving as a bridge between multiple phases (Figure 2B). Within this, the M A phase is characterized by a large angle variation (54.7 ) between [001] PC (T) and [111] PC direction (R), while the M B phase exhibits a smaller angle variation (35.3 ) between [111] PC (R) and [110] PC (orthorhombic phase (O)).…”

High‐performance ferroelectric materials are widely used in various electronic devices owing to the function of mutual conversion among different energies, which mainly relates to their special structure gene of polarization configuration. Recent researches show that the high‐entropy strategy has emerged as an effective and flexible approach for boosting physical properties in high‐entropy ferroelectrics via the delicate design of local polarization configurations and other intrinsic effects caused by entropy increment, such as entropy stabilization, lattice disorder, inhibition of grain coarsening, improved mechanical properties, cocktail effect, and so on. In this review, the recent research progress about high‐entropy ferroelectrics has been summarized, especially for the directional design of novel local polarization configurations according to the characteristics of different electrical properties such as high piezoelectricity, high‐efficiency energy storage, and large electrostriction, providing a guidance for designing and exploring more novel local polarization configurations in high‐entropy ferroelectrics for generating higher performance.image
