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 ...

Fabrication of Textured Bismuth Sodium Titanate Using Excess Bismuth Oxide

Japanese Journal of Applied Physics, 2005
Bi0.5Na0.5TiO3 (BNT) bulk ceramics with a preferred <100> orientation (texture) were prepared by the reactive-templated grain growth method using platelike Bi4Ti3O12 (BiT) particles as templates for BNT. The texture did not develop extensively in stoichiometric BNT, but the addition of excess Bi2O3 to BNT enhanced the texture development. The

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.

ELECTROMECHANICAL CHARACTERIZATION OF LANTHANUM-DOPED SODIUM BISMUTH TITANATE CERAMICS

Modern Physics Letters B, 2006
The effect of lanthanum doping on the electromechanical properties of lanthanum-doped sodium bismuth titanate was studied. The ferroelectric system under investigation was Na 1/2( La x Bi 1-x)1/2 TiO 3 ceramics, with x=0, 0.1, 0.15 and 0.2. Admittance measurements were carried out in the frequency range of 100 Hz to 13 MHz and in the temperature range

Field-induced strain behavior for potassium sodium bismuth titanate ceramics

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007
Data are reported for the dielectric, piezoelectric, electrostrictive, and ferroelectric properties of potassium-substituted sodium bismuth titanate, [(K(x)Na(1-x))(0.5)Bi(0.5)]TiO3. For the morphotropic phase boundary composition x = 0.2, relaxor-type behavior was observed at room temperature with piezoelectric (effective d(333) = 325 x 10(-12) m/V ...

Structural and electrical properties of bismuth magnesium titanate substituted lead-free sodium bismuth titanate ceramics

Journal of Materials Science: Materials in Electronics, 2016
Bismuth magnesium titanate substituted sodium bismuth titanate lead-free piezoceramics are synthesized by solid state reaction method up to x = 0.06 mole fraction. Samples are poled and influence of substitution on poled ceramics is studied. Dielectric, ferroelectric and piezoelectric properties are analyzed in relation with intrinsic parameters strain

Sodium Bismuth Titanate-Based Ceramics

2011
Dielectric, ferroelectric, and piezoelectric properties including phase transition temperatures of perovskite-type bismuth sodium titanate, (Bi1/2Na1/2)TiO3 [BNT]-based lead-free piezoelectric ceramics have been reviewed from the results obtained by our group being superior candidates for lead-free piezoelectric materials to reduce environmental damage.

Peculiarities of phase transitions in sodium-bismuth titanate

Ferroelectrics, 1980
Abstract 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.
