摘要：

The processing conditions, microstructure and dielectric properties of strontium bismuth calcium titanate (SCBT) were studied. SCBT was pre pared 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 degrees 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.
