Уникальные свойства (высокая температура плавления, химическая инертность, термическая стабильность и стойкость к окислению) делают их востребованными в различных промышленных приложениях, включая компоненты, подверженные износу, и термостойкие покрытия. Механическая активация представляет собой эффективный метод механохимического синтеза тугоплавких силицидов, позволяющий получать новые соединения. Характеристики механоактиватора, параметры режима работы и состав исходной смеси играют ключевую роль в эффективности процесса, определяя скорость реакций и фазовый состав конечного продукта. Проведено исследование влияния диаметра измельчающих шаров и времени механической активации на формирование силицидов ниобия при механохимическом синтезе непосредственно из промышленных отходов. Это направление исследований актуально, поскольку позволяет перерабатывать отходы ниобия и кремния, снижая производственные затраты и экологическую нагрузку. Количественно определены изменения массовых долей исходных компонентов (кремния и ниобия) и образовавшихся фаз силицидов (NbSi₂ и Nb₅Si₃) в зависимости от времени активации. Результаты исследования подтвердили пригодность промышленных отходов ниобия и кремния в качестве сырья для синтеза силицидов. Определены оптимальные условия механической активации, позволившие получить порошковую смесь с содержанием силицидов ниобия до 40 мас. %. Полученные материалы продемонстрировали потенциал для применения в составе полимерных электропроводящих покрытий, используемых в качестве электрических нагревателей, антистатических экранов и защиты от электромагнитного излучения. Полученные зависимости электрического сопротивления от температуры нагрева указывают на существование температурно-зависимых процессов, влияющих на проводимость полимерных композитов. Наиболее выраженное снижение сопротивления, свидетельствующее о формировании проводящей структуры, наблюдается в диапазоне 150 ‒ 200 °C, что подчеркивает перспективность разработанных материалов для создания эффективных теплопроводящих элементов и систем защиты от электромагнитных помех.</p></abstract><trans-abstract xml:lang="en"><p>Niobium silicides are promising materials for creating high-temperature composites and heat-resistant alloys capable of operating under extreme conditions. Their unique properties (high melting point, chemical inertia, thermal stability and oxidation resistance) make them in demand in various industrial applications, including wear-resistant components and heat-resistant coatings. Mechanical activation is an effective method of mechanochemical synthesis of refractory silicides, which makes it possible to obtain new compounds. The characteristics of the mechanical activator, the parameters of the operating mode and the composition of the initial mixture play a key role in the efficiency of the process, determining the reaction rate and the phase composition of the final product. The influence of the diameter of grinding balls and the time of mechanical activation on the formation of niobium silicides during mechanochemical synthesis directly from industrial waste has been studied. This area of research is relevant because it allows the recycling of niobium and silicon waste, reducing production costs and environmental burden. The changes in the mass fractions of the initial components (silicon and niobium) and the formed phases of silicides (NBSI₂ and nbsi₃) depending on the activation time were quantified. The results of the study confirmed the suitability of industrial waste of niobium and silicon as raw materials for the synthesis of silicides. Optimal conditions of mechanical activation were determined, which made it possible to obtain a powder mixture with a content of niobium silicides up to 40 % by weight. The obtained materials have demonstrated the potential for use in the composition of polymer electrically conductive coatings used as electric heaters, antistatic shields and protection against electromagnetic radiation. The obtained dependences of electrical resistance on the heating temperature indicate the existence of temperature-dependent processes affecting the conductivity of polymer composites. The most pronounced decrease in resistance, indicating the formation of a conductive structure, is observed in the range of 150 ‒ 200 °C, which underlines the promise of the developed materials for creating effective heat‒conducting elements and protection systems against electromagnetic interference.</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>электрофизические свойства</kwd><kwd>электропроводящие полимерные покрытия</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>electrophysical properties</kwd><kwd>electroconductive polymer coatings</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования по изучению морфологии механоативированных смесей, рентгенофазовому, рентгеноструктурному анализам, зависимости электрического сопротивления от температуры нагрева выполнены в рамках государственного задания ТНЦ СО РАН (проект № FWRF-2024-0009), исследования по подготовки техногенных отходов для механической активации и проведение механической активации проведено при финансовой поддержке проекта FSUN-2024-0005.</funding-statement><funding-statement xml:lang="en">The studies on the morphology of mechanically activated mixtures, X-ray phase, X-ray diffraction analysis, dependence of electrical resistance on heating temperature were supported by the Ministry of Science and Higher Education of the Russian Federation (project No. № FWRF-2024-0009) and studies on the preparation of technogenic waste for mechanical activation and mechanical activation were carried out with financial support of the project FSUN-2024-0005.</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">Tsakiropoulos P.
