Nanocrystalline Pb1−xLaxZr0.52Ti0.48O3 ceramics with x = 0.00, 0.02, 0.04, 0.06 and 0.1 were prepared by the sol gel method. X-ray diffraction analysis of the calcined powder at room temperature shows mixed rhombohedral and tetragonal crystal structure. The grain size increases with the increase in lanthanum concentration. Dielectric properties of the samples were studied as a function of frequency and temperature. The Curie temperature decreases and dielectric constant increases with the… Expand
