Dielectric, ferroelectric and piezoelectric properties of Ca0.5Sr0.5Bi4Ti4O15 prepared by solid state technique

ABSTRACT The processing conditions, microstructure and dielectric properties of strontium bismuth calcium titanate (SCBT) were studied. SCBT was prepared by solid state reactive technique. X-ray diffraction analysis showed the formation of a single-phase layered perovskite structure. Morphological studies were carried out by SEM analysis. Dielectric measurements in the frequency 100 Hz – 1 MHz were made using an Impedance Analyzer (HP4192A) interfaced to a computer and the measurements were carried out from room temperature to 600°C. A variation in the dielectric constant was observed by the incorporation of calcium into the layered perovskite structure. The hysteresis loop revealed a variation in remnant polarization with the substitution of calcium in strontium.
