Освещены результаты научных исследований авторов из разных стран, связанных с изучением влияния допирования титанатов структуры перовскита редкоземельными элементами на их электромагнитные свойства. Содер­жание работы также включает в себя сведения о применении титанатов перовскитоподобной структуры в различных отраслях промышленности. На примере титаната бария (BaTiO3) проведен сравнительный анализ некоторых морфоло­гических свойств (крупность частиц, структура) и электромагнитных характеристик (диэлектрическая проницаемость, температура Кюри, модуль продольных колебаний (d33)) порошков, полученных (и допированных) разными методами. Описаны методики получения BaTiO3 различными способами — сольвотермическим, гидротермалным, золь-гель мето­дом, химическим осаждением и твердофазным спеканием. Представлены результаты исследований влияния изменения технологических параметров (температура, рН, состав исходной смеси материалов и концентрация реагентов) на фазу, морфологию и скорость образования частиц BaTiO3 при гидротермальном синтезе (с использованием в качестве исход­ных материалов BaCl2, TO4 и NaOH). Также в работе приведены результаты экспериментов по изучению влияния мощ­ности микроволнового излучения при твердофазном спекании BaCO3 и ТЮ2 на диэлектрические и сегнетоэлектрические свойства керамики BaTiO3. В результате анализа способов получения BaTiO3 и допирования его редкоземельными эле­ментами установлено, что в настоящее время к наиболее перспективным технологиям получения материалов перовски- топодобной структуры с заданными свойствами можно отнести гидротермальный способ и твердофазное спекание, в том числе с применением СВЧ-излучения.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents an overview of methods for obtaining perovskite structure titanates and doping them with rare-earth elements. The results of scientific research conducted by authors from different countries related to the study of the effect of doping perovskite structure titanates with rare-earth elements on their electromagnetic properties are discussed. The paper also comprises information on the use of perovskite structure titanates in various industries. As exemplified by barium titanate (BaTiO3), a comparative analysis of some morphological properties (particle size, structure) and electromagnetic characteristics (dielectric constant, Curie temperature, modulus of longitudinal oscillations (d33)) of powders obtained (and doped) by different methods is carried out. Techniques for various BaTiO3 preparation methods such as solvothermic, hydrothermal, sol-gel, chemical deposition, and solid-phase sintering are described. The paper provides the results of studies on the effect of changes in process parameters (temperature, pH, composition of the initial mixture of materials and concentration of reagents) on the phase, morphology and BaTiO3 particle formation rate in hydrothermal synthesis (using BaCl2, TiCl4 and NaOH as initial materials). In addition, experiments were conducted to study the effect of microwave radiation power in ВаСОз and ТЮ2 solid-phase sintering on the dielectric and ferroelectric properties of ВаТЮз ceramics. The analysis of methods for obtaining BaTiO3 and doping it with rare-earth elements found that at present the hydrothermal method and the method of solid-phase sintering (including with microwave radiation) can be regarded as advanced technologies for obtaining perovskite structure materials with predetermined properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>титанаты</kwd><kwd>перовскит</kwd><kwd>перовскитоподобная структура</kwd><kwd>синтез</kwd><kwd>методы синтеза</kwd><kwd>допирование</kwd><kwd>мелкодис¬персные порошки</kwd><kwd>наноматериалы</kwd><kwd>наночастицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanates</kwd><kwd>perovskite</kwd><kwd>perovskite structure</kwd><kwd>synthesis</kwd><kwd>synthesis methods</kwd><kwd>doping</kwd><kwd>fine powders</kwd><kwd>nanomaterials</kwd><kwd>nanoparticles</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Fatih Dogan, Hong Lin, Maryline Guilloux-Viry, Octa¬vio Pena.
