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 ...

SYNTHESIS AND CHARACTERIZATION OF LANTHANUM DOPED SODIUM BISMUTH TITANATE

Modern Physics Letters B, 2002
Impedance spectroscopic studies on polycrystalline sintered discs of lanthanum doped Na 1/2( La x Bi 1-x)1/2 TiO 3 ceramics with x = 0, 0.1, 0.15 and 0.2, have been carried out in the temperature region ranging from room temperature to 550°C and in the frequency range of 100 Hz to 1 MHz. Impedance data is presented in frequency explicit plots and Cole–

Substitutional effect of bismuth ferrite on the electrical properties of sodium bismuth titanate ceramics

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.

Modification of dielectric relaxations in sodium bismuth titanate with samarium doping

Journal of Physics and Chemistry of Solids, 2006
Abstract Na0.5Bi(0.5−x) SmxTiO3 (NBST) ceramics with x = 0.05 , 0.1, and 0.15 are prepared through chemical route. The X-ray diffraction studies confirmed the formation of single phase. Dielectric measurements in the temperature region ranging from room temperature (∼30 °C) to 600 °C at different frequencies (10 kHz–1 MHz) showed anomalies ...
