Рассмотрены механизм и условия совместной кристаллизации гидрокарбоалюминатов кальция и магния из предварительно активированного природного Mg-содержащего сырья. Установлена высокая регенерационная способность гексагональных структур синтезированных веществ. Предложена аппаратурно-технологическая схема процесса синтеза гидрокарбоалюминатов щелочно-земельных металлов в условиях глиноземного производства. </p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studying the synthesis kinetics of hydrated magnesium carboaluminates and determines the key role of preceding thermal activation of a raw magnesium component and temperature in the process rate. The study covers the mechanism and conditions of co-crystallization of hydrated calcium and magnesium carboaluminates from the pre-activated natural Mg-containing raw material. It is found that the hexagonal structures of synthesized substances exhibit high regenerative ability. The paper offers a process and instrumentation diagram for synthesizing hydrated carboaluminates of alkali-earth metals in alumina production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминатный раствор</kwd><kwd>синтез</kwd><kwd>температурная активация</kwd><kwd>очистка от примесей</kwd><kwd>гидрокарбоалюминат</kwd><kwd>щелочно-земельные металлы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminate liquor</kwd><kwd>synthesis</kwd><kwd>thermal activation</kwd><kwd>decontamination</kwd><kwd>hydrated carboaluminate</kwd><kwd>alkali-earth metals</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">Сизяков В.М., Тихонова Е.В., Черкасова М.В.
