Properties of nanocrystalline ferroelectric PZT ceramics
Amorphous nanopowders of Pb(Zr 0.5Ti 0.5)O 3 (PZT) solid solution were obtained by sol-gel processing. As-obtained nanopowders ( r ̄ ≈30×10 −9 m) underwent consolidation by conventional ceramic sintering, hot pressing, and rapid thermal annealing. As result of such technological methods PZT ferroele...

−9 m) underwent consolidation by conventional ceramic sintering, hot pressing, and rapid thermal annealing. As result of such technological methods PZT ferroelectric ceramic samples were obtained. They exhibited lack of voids, density close to the theoretical X-ray density, homogeneity from both chemical and physical point of view and stoichiometric chemical composition. It was found that each ceramic sample was a conglomerate of grains exhibiting mean dimension
