Abstract

Amorphous nano-powders of Pb(Zr_0.5Ti_0.5)O₃ (PZT) solid solution were obtained by sol-gel method. As obtained nano-powders of mean dimension rapproximately equals 30 nm underwent consolidation by conventional ceramic sintering, hot high pressing, or rapid thermal annealing. As a result PZT ferroelectric ceramics exhibit lack of voids, density close to the theoretical X-ray density, homogeneity from both chemical and physical point of view and stoichiometric chemical composition. The nanocrystalline structure of the ceramics grains has been revealed by X-ray diffraction method. Dimension of the crystallites (Dequals20-75 nm) were found to depend on temperature (T_s) and the rate of sintering (v_T$. Of the sol-gel-derived powders. Dielectric and piezoelectric properties of the obtained nanocrystalline PZT ceramic samples varied with both sol-gel processing conditions and sintering conditions.
