“…at the perovskite lattices due to the oxidation of Mn 2+ to Mn 3+ and/or Mn 4+ . This is consistent with the results of Mn-substituted 0.62Bi 0.5 Na 0.5 TiO 3 -0.06BaTiO 3 -0.32 (Sr 0.7 Bi 0.2 [] 0.1 ) TiO 3 ceramics [23]. For CBNO-0BM, ferroelectric polarization is slightly pinched at around E = 0 kV/cm (Figures 3(a) and S5(a)) and the measured P-E loop after dc poling (150 kV/cm) is strongly asymmetric with the establishment of a large internal bias field (E ib = 35.1 kV/cm) ( Figure S5(b)).…”

Among Aurivillius-phase ferroelectric ceramics, CaBi 2 Nb 2 O 9 is considered as the best candidate with potential applications in ultrahigh-temperature piezoelectric devices due to the highest T c ( ∼ 940°C). This paper reports that BiMn co-substitution at A and B sites gives rise to dramatic enchantments in ferroelectricity, piezoelectricity, and electrical resistivity of CaBi 2 Nb 2 O 9 ceramics. The optimum composition (Ca 0.97 Bi 2.03 Nb 1.99 Mn 0.01 O 9 ) with a T c of 953 ± 3°C shows a high ferroelectric remnant polarization (P r ), field-induced strain (S 33 ), piezoelectric activity d 33 and d * 33 with values of ∼ 11.1 µC/cm 2 , 4.9 × 10 −4 , 20.8 and 26.1 pC/N, respectively, which are about two to three times those of CaBi 2 Nb 2 O 9 . IMPACT STATEMENTSignificant ferroelectric remnant polarization (P r = 11.1 µC/cm 2 ), field-induced strain (S 33 = 4.9 × 10 −4 ), and piezoelectric activity (d 33 = 20.8 pC/N, d * 33 = 26.1 pC/N) are simultaneously induced in ultrahigh T c CaBi 2 Nb 2 O 9 piezoceramics by BiMn substitution.

W_{normali} (\nabla s) = \frac{normalΓ}{4} \nabla s \cdot \nabla s

“…It has been reported that the dielectric breakdown strength dominates the energy performance in ferroelectric materials compared to the dielectric permittivity, especially under an ultrahigh electric field from the experimental aspect . Furthermore, the energy storage efficiency is considered one of the most important indicators of ferroelectric energy storage ceramics, which is why relaxor ferroelectric ceramics are attracting increasingly more attention in applications of energy storage devices . Such energy storage densities can be easily calculated from electric hysteresis loops.…”

Grain‐size–dependent dielectric properties in nanograin ferroelectrics

A series of ferroelectric ceramic models with grain and grain‐boundary structures of different sizes are established via Voronoi tessellations. A phase‐field model is introduced to study the dielectric breakdown strength of these ferroelectric ceramics. Afterward, the relation between the electric displacement and electric field and the hysteresis loop are calculated using a finite element method based on a classical and modified hyperbolic tangent model. The results indicate that as the grain size decreases, the dielectric strength is enhanced, but the dielectric permittivity is reduced. The discharge energy density and energy storage efficiency of these ferroelectric ceramics extracted from the as‐calculated hysteresis both increase along with a decrease in their grain size at their breakdown points. However, under the same applied electric field, the ferroelectric ceramic with a smaller grain size possesses a lower discharge energy density but a higher energy storage efficiency. The results suggest that ferroelectric ceramics with smaller grain sizes possess advantages for applications in energy storage devices.

“…For example, BaTiO 3 -Bi(Mg 2/3 Nb 1/3 )O 3 [13] exhibited a high relative permittivity (~6800). Binary solid solution based on (Bi 0.5 Na 0.5 )TiO 3 -BaTiO 3 was a candidate in hightemperature energy-storage application [14][15][16][17]. BaTiO 3 -BiYO 3 ceramics could meet the X9R criterion [18].…”

Ba 1-x Bi 0.67x Na 0.33x)(Ti 1-x Bi 0.33x Sn 0.67x)O 3 (abbreviated as BBNTBS, 0.02 ≤ x ≤ 0.12) ceramics were fabricated via a traditional solid state reaction method. The phase transition of BBNTBS from tetragonal to pseudo cubic is demonstrated by XRD and Raman spectra. The BBNTBS (x = 0.1) ceramics have decent properties with a high ε r (~2250), small Δε/ε 25°C values of ±15% over a wide temperature range from-58 to 171 ℃, and low tanδ ≤ 0.02 from 10 to 200 ℃. The basic mechanisms of conduction and relaxation processes in the high temperature region were thermal activation, and oxygen vacancies might be the ionic charge transport carriers. Meanwhile, BBNTBS (x = 0.1) exhibited decent energy storage density (J d = 0.58 J/cm 3) and excellent thermal stability (the variation of J d is less than 3% in the temperature range of 25-120 ℃), which could be a potential candidate for high energy density capacitors.
