Field-induced strain behavior for potassium sodium bismuth titanate ceramics
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007Data 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 ...

Journal of Materials Science: Materials in Electronics, 2015
Lead free sodium bismuth titanate ceramics was substituted with bismuth ferrite in low mole fraction and the influence of substitution on the dielectric constant, Curie temperature, depolarization temperature, remnant polarization, coercive field and piezoelectric coefficient were studied. Rhombohedral R3c symmetry is maintained for all mole fractions.

Structural Optimization of Bismuth Sodium Titanate Thin Films
Ferroelectrics, 2015Lead-free ferroelectric oxide materials have attracted considerable attention from the environmental viewpoint. Among lead-free piezoelectric materials, bismuth sodium titanate (Bi0:5Na0:5TiO3) is considered to be one of the excellent candidates.

Hydrothermal synthesis of bismuth sodium titanate particles with different morphologies
Journal of Materials Science, 2013Nanostructured Na0.5Bi0.5TiO3 particles have been synthesized by a hydrothermal synthesis method using a layered titanate H1.07Ti1.73O4·nH2O as a Ti precursor. The obtained Na0.5Bi0.5TiO3 particles showed different morphologies including plate-like, wire-like, and cubic-like structures in different hydrothermal conditions.
