“…BTN-based ceramic is a typical even-layered Aurivillius phase compound with second ferro-paraelectric phase transition. The loss peak observed here is probably owing to the displacement of domain walls [27]. Besides, the temperature dependent dielectric behavior coefficient (vε/vT) in the temperature range of 30e600 C decreases from 0.40 to 0.24 C À1 with the incorporation of the Ta and W doping.…”

“…Since the T c or maximum dielectric constant temperature, T m , of all of the solid solutions, ͑CBNO͒ 1−x ͑BBNO͒ x , was higher than 200°C, the ferroelectric P -E hysteresis loops were measured at 25 and 200°C and 10 Hz using a ferroelectric hysteresis measurement tester ͑NPL, U.K.͒. 26 The measurement procedure involved the application of triangular voltage waveforms with two complete cycles to the test samples. Samples for piezoelectric measurements were poled in silicone oil at different temperatures ͑100 and 200°C͒ under dc electric field strengths from 8 to 11 kV/mm for 5-15 min depending on their bulk conductivities.…”

Articles you may be interested inThe microstructures and electrical properties of Aurivillius phase ferroelectric solid solutions of ͑CaBi 2 Nb 2 O 9 ͒ 1−x ͑BaBi 2 Nb 2 O 9 ͒ x ͑0 Յ x Յ 1͒ have been studied. X-ray diffraction analyses revealed a bismuth layered structure for all compositions. Scanning electron microscope images showed randomly oriented and platelike grain morphology. The Curie point T c or the maximum permittivity temperature T m decreased with increasing x. The ͑CaBi 2 Nb 2 O 9 ͒ 1−x ͑BaBi 2 Nb 2 O 9 ͒ x ceramics exhibited a ferroelectric-paraelectric phase transition at small x values ͑x Յ 0.5͒, whereas a relaxor behavior was observed at high x values ͑x Ն 0.8͒. The d 33 value of CaBi 2 Nb 2 O 9 ceramics was enhanced by Ba 2+ doping on the A-sites ͑x Յ 0.3͒. A combination of high d 33 values and high T c points ͑Ͼ700°C͒ suggests that compositions with x Յ 0.3 could be good candidates for high-temperature piezoelectric applications. The composition with x = 0.8 is a relaxor ferroelectric with T m around 320°C at 1 MHz.

“…4 It is expected that the substitution on the A sites by other lanthanides with smaller ionic radius than that of Bi or La can further improve the ferroelectric properties. 10 More recently, Kojima and co-workers 8,10 and Chon and co-workers 11 15 Based on the fact that the anisotropies of the lattice constants of the a and b axes decrease for Bi 3−x Sm x NbTiO 9 ceramics with increasing content of Sm substitution, Sugaya et al 16 predicted that the piezoelectric properties of Ln ͓Ln= La, Nd, Sm, r͑Sm 3+ ͒ = 1.24 Å ͑Ref. 14͒ and Gd, r͑Gd 3+ ͒ = 1.107 Å ͑Ref.…”

Effect of lattice occupation behavior of Li+ cations on microstructure and electrical properties of (Bi1/2Na1/2)TiO3-based lead-free piezoceramics J. Appl. Phys. 109, 054102 (2011) The effect of Nd substitution on the microstructures and electrical properties of Aurivillius phase ferroelectric Bi 3 NbTiO 9 -based ceramics has been studied. All of the Bi 3−x Nd x NbTiO 9 ͑0 Յ x Յ 1͒ ceramics are ferroelectrics. The Curie point T C decreased with increasing Nd doping content x. The Bi 3−x Nd x NbTiO 9 ceramics exhibited a sharp ferroelectric-paraelectric phase transition at small x values ͑x Յ 0.6͒, whereas a diffuse phase transition was observed at higher x values ͑x Ն 0.8͒. Both the piezoelectric constant d 33 and the dc electrical resistivity of Bi 3 NbTiO 9 ceramics were greatly enhanced by Nd substitution on the A sites. The improved properties can be attributed to the fact that Nd substitution depressed the generation of oxygen vacancies. A combination of high d 33 values, high resistivity, and high T C points ͑Ͼ700°C͒ suggests that the Bi 3−x Nd x NbTiO 9 ceramics with x Յ 0.6 could be good candidates for high-temperature piezoelectric applications.
