Показано, что термическая обработка этих интермедиатов при 850 °С/2 ч позволяет получить монофазные порошки  голландитоподобных твердых растворов состава K1,70Mn1,66Al0,81Ti5,52O16 и K1,76Mn1,60Al0,39Сr0,45Ti5,48O16 соответственно. На основе компактированных порошков полученных продуктов изготовлены керамические диэлектрики, спеченные при 1080 °С/3 ч. Электрические свойства полученных образцов исследованы методами импедансной спектроскопии. Показано, что частичная замена Al на Cr в составе интермедиата  увеличивает диэлектрическую проницаемость (от 820 до 1580) и снижает диэлектрические потери (от 0,89 до 0,22) на рабочей частоте 1 кГц. При этом введение обоснованной комбинации допантов (Nb2O5, 0,5 %; Nd2O3, 0,3 %; LiF, 0,8 %) и флюсообразующей добавки (борат цинка, 2 %) позволяет добиться существенного увеличения диэлектрической проницаемости (до 57800 ± 600) и снижения диэлектрических потерь (tg(δ), до 0,084 ± 0,02), а также увеличивает температурную стабильность диэлектрической проницаемости керамики в интервале от –55 до +125 °С до уровня требований к диэлектрикам категории Х7Т.</p></abstract><trans-abstract xml:lang="en"><p>Intermediates to produce ceramic powders were synthesized using amorphous potassium polytitanate (K2O×4TiO2×xH2O, PPT) modified in aqueous solutions of mixtures of manganese and aluminum sulfates, taken in a 2 : 1 molar ratio, and manganese, aluminum, and chromium sulfates, taken in a 2 : 1/2 : 1/2 molar ratio. It was shown that heat treatment of these intermediates enables the synthesis of single-phase powders of hollandite-like solid solutions K1.70Mn1.66Al0.81Ti5.52O16 and K1.76Mn1.60Al0.39Сr0.45Ti5.48O16, respectively. Ceramic dielectrics were fabricated using compacted powders of the obtained products, which were sintered at 1080 °C/3 h. The electrical properties of the ceramic specimens produced were investigated by impedance spectroscopy methods. It was shown that partial replacement of Al with Cr in the intermediate composition increases the permittivity (from 820 to 1580) and reduces dielectric loss (tg(δ), from 0.89 to 0.22). Moreover, some justified doping additives (Nb2O5, 0.5 %; Nd2O3, 0.3 %; LiF, 0.8 %) and a flux (zinc borate, 2%) allow for a further increase in dielectric constant (up to 57,800 ± 600), decrease of tg(δ) (down to 0.084 ± 0.02) and significantly increase the temperature stability of permittivity for the obtained ceramics in the temperature range from  –55 to +125 °C up to the level corresponding to a X7T category of dielectrics.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>титанаты</kwd><kwd>голландитоподобные твердые растворы</kwd><kwd>керамика</kwd><kwd>синтез</kwd><kwd>диэлектрическая проницаемость</kwd><kwd>диэлектрические потери</kwd></kwd-group><kwd-group xml:lang="en"><kwd>: titanates</kwd><kwd>hollandite-like solid solutions</kwd><kwd>ceramics</kwd><kwd>synthesis</kwd><kwd>permittivity</kwd><kwd>dielectric losses</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">Carter CB, Norton MG.
