Abstract To optimize the electrical properties of lead zirconate titanate, it was modified by calcium. Pb1−xCaxZr0.52Ti0.48O3, x=0.00, 0.02, 0.04, 0.06 and 0.10 composition, was prepared by the sol–gel technique. All the samples have been crystallized to a mixture of rhombohedral and tetragonal crystallographic phases. The dielectric constant increases with the increase in calcium concentration due to the increase in electronic polarization. The Curie temperature decreases with increase in… Expand
