Description

SrBi2Ta2O9/SBT, Sr0.8Bi2.15Ta2O9/SBexT and SrBi2(Ta0.925W0.075)2O9/SBTW, 2-layered perovskite ferroelectric ceramic samples were prepared in single phase by solid-state reaction technique. Similar crystal structure was observed from the XRD study of the calcined powders of all the SBT based systems. Enhanced transition temperature (Tc), dielectric constant (εr) and ferroelectric properties were observed in both the SBexT and SBTW ceramic samples compared to the pure SBT ceramic samples. The higher remnant polarization (Pr)~8.07 μC/cm2 and lower coercive field (Ec)~15.18 kV/cm were observed in the SBexT ceramic samples. The bipolar fatigue study was carried out and the normalized polarization vs. number of cycles (up to 109) behavior confirmed the fatigue resistant nature of all the SBT based ceramic samples. In comparison to the pure SBT ceramic samples, decreased leakage current with increased piezoelectric properties were observed in both the SBexT and SBTW ceramic samples.
