Hydrothermal synthesis of PLZT powders

La-modified lead zirconate titanate ( PZT) ceramics have been prepared using the hydrothermal process. Temperature effect on PLZT powders has been studied using TGA-TDA technics, Fourier Transform Infrared (FTIR) spectroscopy, and X-Ray Diffraction (XRD).Dielectric measurements have also been performed. Crystallization temperature has been found to be inferior to that reported in the literature, relative to analogous compounds prepared using other methods. All the obtained results have been discussed and compared to those reported in the literature.
