Механическая активация (МА) является эффективным методом как для подготовки порошков, так и для получения материалов механохимическим синтезом. Этот процесс включает комплекс взаимосвязанных физико-химических явлений: интенсивная пластическая деформация, накопление дефектов, измельчение, формирование слоистых агломератов с увеличенной межфазной поверхностью. Все это позволяет управлять и контролировать кинетику реакций и формировать фазовый состав порошковой смеси. Изучена возможность синтеза силицидов ниобия из техногенных отходов: ниобиевой стружки и кремниевых пластин. Исследованы подготовка сырья, измельчение и удельная поверхность активированных смесей при различном времени механической активации. Рентгенофазовый анализ подтвердил формирование силицидов ниобия. Эксперименты показали возможность и целесообразность использования отходов в качестве исходного сырья. Были подобраны условия механической активации для получения кристаллической порошковой смеси с суммарным содержанием силицидов ниобия, достигающим 38 мас. %. Полученные результаты закладывают основу для дальнейшей оптимизации МА с целью направленного синтеза материалов для нового поколения высокотемпературных композитов.</p></abstract><trans-abstract xml:lang="en"><p>Niobium silicides are of scientific and applied interest for high-temperature composite materials due to their thermal stability and mechanical strength. Mechanical activation (MA) is an effective method both for the preparation of powders and for the production of materials by mechanochemical synthesis. This process includes a complex of interrelated physico-chemical phenomena: intense plastic deformation, accumulation of defects, crushing, formation of layered agglomerates with an enlarged interfacial surface. All this allows you to control and control the kinetics of reactions and form the phase composition of the powder mixture. The possibility of synthesizing niobium silicides from technological waste: niobium chips and silicon wafers has been studied. The preparation of raw materials, grinding and specific surface area of activated mixtures at different times of mechanical activation are investigated. X-ray phase analysis confirmed the formation of niobium silicides. Experiments have shown the possibility and expediency of using waste as a feedstock. The conditions of mechanical activation were selected to obtain a crystalline powder mixture with a total content of niobium silicides reaching 38 % by weight. The results obtained lay the foundation for further optimization of the MA in order to synthesize materials for a new generation of high-temperature composites.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ниобий</kwd><kwd>кремний</kwd><kwd>силициды ниобия</kwd><kwd>механическая активация</kwd><kwd>механохимический синтез</kwd><kwd>технологическая обработка</kwd><kwd>техногенные отходы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>niobium</kwd><kwd>silicon</kwd><kwd>niobium silicides</kwd><kwd>mechanical activation</kwd><kwd>mechanochemical synthesis</kwd><kwd>processing</kwd><kwd>man-made waste</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">Sankar M., Satya Prasad V.V., Baligidad R.G., Alam M.Z., Das D.K., Gokhale A.A.
