Синтез осуществляли из порошковых смесей состава 2Ti/TiC/Al с введением 1 и 3 мас.% кремнийсодержащих добавок. Подготовка шихты включала механоактивацию в планетарной шаровой мельнице в течение 24 часов, обеспечивающую повышение реакционной способности исходных компонентов, после чего проводили реакционное спекание при температуре 1400°C в атмосфере аргона. Методами рентгенофазового анализа и сканирующей электронной микроскопии установлено, что введение nSi и SiO₂ оказывает существенное влияние на фазовый состав, дефектность и морфологию синтезируемых материалов, а также на кинетику фазообразования. Показано, что добавка 1 мас.% nSi способствует формированию более однородной MAX-фазной структуры Ti₃AlC₂ и снижению доли остаточного TiC за счёт интенсификации диффузионных процессов. Введение SiO₂ приводит к формированию дефектной и пористой структуры с возможным участием оксидных компонентов, что может ограничивать полноту образования целевой фазы. Полученные результаты демонстрируют перспективность использования кремнийсодержащих добавок для направленного управления структурой и свойствами материалов на основе MAX-фаз в процессе низкотемпературного твёрдофазного синтеза и оптимизации их эксплуатационных характеристик.</p></abstract><trans-abstract xml:lang="en"><p>This study investigates the effect of nanoscale additives of elemental silicon (nSi) and silicon dioxide (SiO₂) on the solid-state synthesis of the MAX phase Ti₃AlC₂. The synthesis was carried out using powder mixtures with a composition of 2Ti/TiC/Al containing 1 and 3 wt.% silicon-containing additives. Powder preparation included mechanical activation in a planetary ball mill for 24 hours, which enhanced the reactivity of the initial components, followed by reactive sintering at 1400°C in an argon atmosphere. X-ray diffraction and scanning electron microscopy revealed that the addition of nSi and SiO₂ has a significant effect on the phase composition, defect structure, and morphology of the synthesized materials, as well as on the kinetics of phase formation. It was shown that the addition of 1 wt.% nSi promotes the formation of a more homogeneous MAX-phase Ti₃AlC₂ structure and reduces the amount of residual TiC due to intensified diffusion processes. The introduction of SiO₂ leads to the formation of a defective and porous structure with possible involvement of oxide components, which may limit the completeness of target phase formation. The obtained results demonstrate the prospects of using silicon-containing additives for targeted control of the structure and properties of MAX-phase-based materials during low-temperature solid-state synthesis and optimization of their performance characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>MAX-фаза</kwd><kwd>Кремний</kwd><kwd>Рисовая шелуха</kwd><kwd>Диоксид кремния</kwd><kwd>MXene</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MAX phase</kwd><kwd>silicon</kwd><kwd>rice husk</kwd><kwd>silicon dioxide</kwd><kwd>MXene</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование финансировалось Комитетом науки, Министерства науки и высшего образования Республики Казахстан (грант № BR24992873).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Smetkin A.A.
