Установлено, что лимитирующей стадией является взаимодействие фаз со структурами перовскита (Sr9Ni7O21), K2NiF4 (Sr2(Ti, Me)mNi1-mOy) и SrO. Неустойчивость оксидов Sr2(Ti, Me)mNi1-mOy (Me - Mo, Ta, Nb) при температурах синтеза обусловливает особенности механизма и определяет лимитирующие стадии, открывая тем самым возможности управления ходом многостадийного твердофазного процесса.</p></abstract><trans-abstract xml:lang="en"><p>The formation mechanism of perovskite-like layered compounds Sr4Ni1,8Me0,1Ti0,1Ox (Me - Mo, Ta, Nb) crystallizing in the Sr3Ti2O7-type of structure has been investigated. It has been found that the limiting step is interaction of phases with the perovskite-type structure (Sr9Ni7O21), K2NiF4 (Sr2(Ti, Me)mNi1-mOy) and SrO. Instability of oxides Sr2(Ti, Me)mNi1-mOy (Me - Mo, Ta, Nb) at synthesis temperatures determines the specific features of the mechanism and limiting stages, thereby opening the possibility for controlling the multistep solid state process.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ruddlesden S.
