Abstract

Characterization of the electromechanical properties of (1-x)(Bi0.5Na0.5)TiO3-xBaTiO(3) was attempted over a range of composition near the morphotropic phase boundary (MPB) region. A complete set of electromechanical properties were determined using the results of impedance resonance spectroscopy carried out for the thickness-extension and length-extension modes of the piezoceramic resonators. Room temperature properties depicted a strong compositional dependence while the coupling and piezoelectric properties reaching maxima at x = 0.07 for both the resonance modes. Strain-field hysteresis loops traced at room temperature for the composition x = 0.07 under moderate electric fields revealed high values of recoverable strain and inverse piezoelectric coefficient.
