Показано, что за счет программируемого изменения концентрации реакционной среды в ходе сольвотермического синтеза можно эффективно управлять процессами зародышеобразования и роста оксидных частиц и получать частицы метастабильного гексагонального триоксида молибдена в виде правильных призматических кристаллов со средним размером от 200—500 нм до 10 мкм.</p></abstract><trans-abstract xml:lang="en"><p>   The processes of formation and dispersion of monoclinic and hexagonal molybdenum trioxide phases during the course of thermoinduced polycondensation of molybdic acid in aqueous medium at 100 °C were investigated with the use of dynamic light scattering technique. It has been shown that programmed changing of the concentration of the reaction medium makes it possible to exert an effective control over the nucleation and particle growing in the solution and permits one to obtain perfect prismatic crystallites of metastable hexagonal molybdenum trioxide with the medium size from 200–500 nm to 10 μm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамическое светорассеяние</kwd><kwd>поликонденсация</kwd><kwd>молибденовая кислота</kwd><kwd>моноклинный триоксид молибдена</kwd><kwd>гексагональный триоксид молибдена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamic light scattering</kwd><kwd>polycondensation</kwd><kwd>molybdic acid</kwd><kwd>monoclinic molybdenum trioxide</kwd><kwd>hexagonal molybdenum trioxide</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках задания государственной программы научных исследований “Фотоника и электроника для инноваций”, подпрограмма “Микро и наноэлектроника” 3.11.4 (номер государственной регистрации 20212675)</funding-statement><funding-statement xml:lang="en">The work was performed within the framework of the assignment of the state research program “Photonics and Electronics for innovation”, subprogram “Micro and nanoelectronics” 3.11.4 (state registration number 20212675)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">J.-P.
