Проведенные исследования позволили определить наиболее рациональные режимы обработки с использованием планетарно-центробежной мельницы АГО-2: время активации 20 мин при соотношении материал : шары, равном 1 : 3. Установлены зависимости среднего размера частиц, общей поверхности и изменения их фазового состава от условий активации. Показано, что после обработки средний размер частиц глинозема уменьшается с 3,2 до 1,6 мкм при увеличении их общей поверхности от 31·103 до 61·103 см2/см3. Также наблюдается уширение рентгеновских линий без уменьшения их интенсивности, следовательно, в ходе активации при распаде гиббсита γ-Al2O3 новые фазы не образуются. В механоактивированном глиноземе представлены две фракции: исходный α-Al2O3, имеющий размеры кристаллитов порядка 1 мкм (что соответствует его весьма узким линиям на рентгенограммах исходного глинозема), и мелкодисперсный α-Al2O3 с размерами кристаллитов примерно 0,1 мкм (что обычно отвечает начальной стадии уширения линий фазы), образовавшийся в результате распада гиббсита.</p></abstract><trans-abstract xml:lang="en"><p>The influence of regimes of mechanical activation on geometric, energetic, and chemical parameters of activation of alumina used as a component of dressing coatings. The studies made it possible to determine the most rational treatment modes, notably, using an AGO-2 planetary-centrifugal mill: activation time is 20 min at material : balls ratio of 1 : 3. The dependences of the average particle size, the total surface, and variation in their phase composition on activation conditions are established. It is shown that the average particle size of alumina particles decreases from 3,2 to 1,6 μm with an increase in their total surface from 31·103 to 61·103 cm2/cm3. X-ray lines also broaden without decreasing their intensity; consequently, now new phases are formed in the course of activation during the decomposition of gibbsite γ-Al2O3. Two fractions are present in mechanically activated alumina, notably, initial α-Al2O3 having the crystallite size of the order of 1 μm (which corresponds to its very narrow lines in X-ray diffraction patterns of initial alumina) and finely dispersed α-Al2O3 with crystallite sizes approximately of 0,1 μm (which usually corresponds to the initial broadening stage of the lines of a new phase), which is formed due to the decomposition of gibbsite.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глинозем</kwd><kwd>механоактивация</kwd><kwd>средний размер частиц</kwd><kwd>фракционный состав</kwd><kwd>общая поверхность</kwd><kwd>геометрические параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alumina</kwd><kwd>mechanical activation</kwd><kwd>average particle size</kwd><kwd>fractional composition</kwd><kwd>total surface</kwd><kwd>geometric parameters</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">Vybor ogneupornykh pokrytii dlya okraski sterzhnei i form [The choice of refractory coatings for painting of rods and shapes: Mater.
