Показано, что с ростом температуры осаждения кремнегеля структурные параметры полученных образцов силикагеля сильно изменяются. Рассмотрен механизм структурообразования и указаны основные причины, ответственные за этот процесс. Установлено, что с ростом концентрации раствора силиката натрия при постоянной температуре осаждения гидроксидов, сорбционная емкость образцов увеличивается, а удельная поверхность, наоборот, уменьшается. Показано, что обработка отмытого кремнегеля в кипящей воде способствует развитию его сорбционной емкости и увеличению удельной поверхности. </p></abstract><trans-abstract xml:lang="en"><p>The relationship between the temperature of silicic acid gel deposition and the structure of silica formed, has been studied. It has been shown that, with increasing deposition temperature of silicic acid gel, structural parameters of silica samples obtained change greatly. The mechanism of structure formation has been considered and the main causes responsible for this process have been identified. It has been found that with increasing concentration of sodium silicate solution at constant precipitation temperature, the sorption capacity of samples increases while the specific surface area decreases. It has been shown that treatment of washed silica gel in boiling water improves its adsorption capacity and reduces its specific surface.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адсорбция</kwd><kwd>термосинтез</kwd><kwd>кремнегель</kwd><kwd>структурообразование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silica thermosynthesis</kwd><kwd>adsorption</kwd><kwd>structure formation</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">Smoluchowski, M.
