Воспроизведена и уточнена фазовая диаграмма для CaSiO3. Рассмотрены возможные механизмы вхождения алюминия в исследуемые структуры. По результатам расчетов Al предпочтительнее входит в структуру MgSiO3, чем в CaSiO3. Оценка изоморфной емкости перовскитовых фаз по Al показала, что для MgSiO3 она может достигать 2,4 мол.% при 120 ГПа и 2400 К. CaSiO3 не может являться контейнером для атомов алюминия в мантии Земли.</p></abstract><trans-abstract xml:lang="en"><p>Current paper presents semi-empirical and quantum chemistry theoretical investigations of Al atoms energy occurrences in CaSiO3 and MgSiO3 with perovskites structures under Earth’s mantle thermodynamic conditions. The phase diagram of CaSiO3 was reproduced and refined. Possible mechanisms of aluminum atoms incorporation into structures were investigated. The results of the calculations indicate that aluminum is preferably included in the MgSiO3 than СaSiO3. Perovskite phases isomorphic capacity evaluation for Al showed that in MgSiO3 this value can reach 2.4 mol.% at 120 GPa and 2400 K. CaSiO3 can’t be a container for the aluminum atoms in the Earth’s mantle.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерное моделирование</kwd><kwd>дефекты в перовскитах</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Al-со держащие перовскиты</kwd><kwd>CaSiO3</kwd><kwd>computer modeling</kwd><kwd>defects in perovskites</kwd><kwd>Al containing perovskites</kwd><kwd>CaSiO3</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">Пущаровский Ю.М., Пущаровский Д.Ю.
