Аннотация: In present review are presented the results of investigations in field of using of new mechanochemical method for synthesis of piezoelectrics obtained by different authors.The PZT ceramic powders were successfully prepared by mechanochemical synthesis in planetary ball mill using different compositions of initial reagents. The initПоказать полностьюial components were lead oxides as orthorhombic and tetragonal PbO, Pb3O4, PbO2, titanium oxides TiO2 as rutile and anatase and TiO, monoclinic zirconium oxide ZrO2, hydrated oxides and pure metals of titanium and zirconium. The possibility to obtain lead zirconate-titanate as early as during mechanical activation of samples was demonstrated. In some systems cubic lead oxide Pb2O is formed during mechanical activation; then it disappears completely at annealing at 400°C. Changes in the structure and chemical composition of samples during annealing were investigated. The final formation of lead zirconate-titanate structure occurs at the annealing of samples in the temperature range from 1000 up to 1100°C depending on the initial components. The formation of nanodispersed structures with the grain size 10 - 40 nm was demonstrated by X-ray diffraction and TEM. The complex perovskite structures is successfully synthesized by mechanical activation of mixed oxides composition, followed by sintering at elevated temperatures. It is shown that they exhibit a considerable stable temperature dependence of dielectric constant over the wide temperature range. © 2012 by Nova Science Publishers, Inc. All rights reserved.
