The PLZT ceramics was sintered by the hot-pressing method from sol-gel derived powders. The samples obtained exhibited lack of voids, and the density close to the theoretical X-ray values. They were homogeneous from the chemical and physical points of view and exhibited stoichiometric chemical compositions. Dimensions of the crystallites depended on the temperature of sintering of the amorphous nanopowders. Dielectric and ferroelectric properties of the nanocrystalline PLZT ceramics were studied and relationships between their properties and processing conditions were revealed.
