摘要
Ceramics in the system (1-x)Na0.5Bi0.5TiO3-xBa(0.80)Ca(0.20)TiO(3) demonstrate a phase boundary between pseudo-cubic and tetragonal at 0.1 < x < 0.2. There was a gradual convergence in the temperatures of a frequency-dependent inflection and peak in relative permittivity-temperature plots with increasing x: for x=0.5 and 0.6, normal relaxor-like behaviour was observed, with T-m similar to 150 degrees C (1 kHz). Constriction in the polarisation-electric field hysteresis loops for the phase boundary composition x=0.1 was consistent with an electric field-induced phase transition, giving rise to an electromechanical strain, similar to 0.25 % at 40 kV/cm and high-field d(33)* similar to 640 pm/V.
