High Field Electroformation of Sodium Bismuth Titanate
SSRN Electronic Journal, 2020Lead-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 ...

Piezoelectricity and Flexoelectricity of Sodium Bismuth Titanate-Based Ceramics
Ceramics International, 2020Abstract 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 ...

Hydrothermal Synthesis of Sodium Bismuth Titanate Ferroelectrics
Inorganic Materials, 2020We 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.

Preparation and Properties of Lead Free Bismuth Sodium Titanate−Bismuth Zinc Titanate Ceramics
Ferroelectrics, 2009Lead-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.

Abstract Lead-free bismuth sodium titanate-bismuth potassium titanate-barium titanate ceramic/cement composites with carbon nanotubes (CNTs) addition were developed for smart structures application. The pores in composite and insulating nature of the cement matrix made the poling difficult and lower piezoelectric activities of composites.

Peculiarities of phase transitions in sodium-bismuth titanate
Ferroelectrics, 1980Abstract The ferroelectric properties of (Na0,5Bi0,5TiO3) single crystals are studied. It is found that some physical characteristics possess a large temperature hysteresis in the temperature range 200 – 300°C. The nature of that hysteresis is discussed.

Hydrothermal Synthesis of Sodium and Potassium Bismuth Titanates
Chemistry of Materials, 2000A thermodynamic model of electrolyte solutions has been used as a tool for equilibrium calculations in the Na−Bi−Ti−H2O and K−Bi−Ti−H2O systems. To perform the calculations, unknown standard-state properties for Na0.5Bi0.5TiO3 (NBT), K0.5Bi0.5TiO3 (KBT) and other solid compounds that exist in these systems were established.

Hydrothermal Synthesis of Sodium Potassium Bismuth Titanates
Ferroelectrics, 2015(Bi0.5Na0.5)TiO3 (BNT) is an excellent candidate lead-free piezoelectric material system. This study prepares BNT ceramics using the hydrothermal method at 180°C with an NaOH concentration of 12 M. The effect of potassium content on the crystal structure of the ceramics is studied.

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.
