Lead Zirconate Titanate (PZT) nanopowder of ratio 35/65 (Pb(Zr 0.35 Ti 0.65 )O 3 is prepared by one of the most wet-chemical routes called Sol-Gel Processing Method. The Lead Zirconate Titanate (PZT) is prepared from Lead Acetate and Zirconate (IV) isopropoxide as a source of metals. The acetic acid can be used as a solvent, and 2-methoxy was used as a stabilizer for Titanate (IV) isoproxide. The heat-treated powders at different sintering temperatures are characterized using the XRD diffraction technique, SEM, and LCR meter. XRD pattern shows the tetragonal phase of 35/65 Zr/Ti composition. They exhibited high density which is slightly different from the theoretical density, decrease of voids, stoichiometric chemical material, and homogeneity from both physical and chemical material. It has been found that each ceramic sample was exhibited different particles size depending on sintering temperature. The present work is well-crystallized with nanoparticles and single-phase perovskite PZT powders that can be obtained after heat treatment above 550°C for two hours. The dependence of this crystallization temperature is observed on the preparation condition. Lattice constant distortion is realized on dielectric constant, especially on the tetragonal phase.
