Piezoelectricity and flexoelectricity of sodium bismuth titanate-based ceramics

Ceramics International, 2020
Abstract Although sodium bismuth titanate-based lead-free piezoelectric ceramics are a good substitute for lead oxide-based piezoelectric ceramics, their piezoelectric properties are still inferior to those of lead oxide-based ceramics. In this paper, the variation of piezoelectricity of sodium bismuth titanate-barium titanate (NBBT) ceramics after ...

High Field Electroformation of Sodium Bismuth Titanate

SSRN Electronic Journal, 2020
Lead-free ceramics based on Na1/2Bi1/2TiO3 (NBT) have been shown to exhibit excellent ferroelectric properties putting them amongst the best materials to replace lead-based piezoelectrics. The defect chemistry of NBT is, however, very complex. High oxygen ionic conductivity can be induced by acceptor doping or bismuth evaporation, which is quite ...

Hydrothermal Synthesis of Sodium Bismuth Titanate Ferroelectrics

Inorganic Materials, 2020
We have studied phase formation processes during sodium bismuth titanate, Na0.5Bi0.5TiO3 (NBT), synthesis under hydrothermal conditions at a temperature of 230°C for 24 and 48 h using stoichiometric mixtures of titanium oxide and bismuth hydroxide and NaOH solutions in the concentration range 5–30 M.

Enhanced bulk conductivity of A-site divalent acceptor-doped non-stoichiometric sodium bismuth titanate [PDF]

Solid State Ionics, 2017
Bismuth-deficient sodium bismuth titanate (nominally Na0.5Bi0.49TiO2.985, NB0.49T) is a good oxide-ion conductor. Here we report the influence of A-site divalent ions, M2 + = Ca2 +, Sr2 + and Ba2 +, on the electrical properties of NB0.49T.

Preparation and Properties of Lead Free Bismuth Sodium Titanate−Bismuth Zinc Titanate Ceramics

Ferroelectrics, 2009
Lead-free piezoelectric ceramics based on (1–x)Bi 1/2 Na 1/2 TiO 3 – x Bi(Zn 1/2 Ti 1/2 )O 3 (x = 0.0, 0.02, 0.04, 0.06, 0.08, 0.10, 0.20, 0.30, 0.40, and 0.5) were obtained via solid-state processing techniques. The influence of BZT addition on BNT characteristics, sintering, microstructure and properties was investigated.
