Проведена оптимизация стандартной методики восстановления хлорида меди(I) с целью получения мелкодисперсных частиц меди, обладающих высокой каталитической активностью. Показано, что восстановление возможно непосредственно в контакте с кремнием, полученный средний диаметр частиц меди составляет 5–10 мкм в обеих контактных массах (25%Cu-75%Si и 50%Cu-50%Si). Металлографический анализ показал рыхлую морфологию поверхностей раздела фаз кремний-медь, что необходимо для усиления каталитической активности контактных масс. Локальным химическим анализом методом растровой электронной микроскопии установлено соотношение размера частиц исходных поликристаллов хлорида меди(I) и полученных частиц меди в результате восстановления на кремнии. Глубокое восстановление позволяет получать частицы размером до 5 мкм. Полученные результаты представляют интерес для производства покрытий на основе кремнийорганических соединений, снижающих трение при транспорте углеводородов.</p></abstract><trans-abstract xml:lang="en"><p>Two contact masses were obtained and analyzed for their catalytic properties in the production of hydrophobic coatings. These masses are based on the silicon-copper system and consist of 25%Cu-75%Si and 50%Cu-50%Si compositions. A standard method of copper(I) chloride reduction was optimized to obtain finely dispersed copper particles with high catalytic activity. It is shown that reduction is possible directly in contact with silicon, the resulting average diameter of copper particles is 5-10 microns in both contact masses (25%Cu-75%Si and 50%Cu-50%Si). A metallographic analysis revealed a loose morphology of the silicon-copper phase interfaces, which is necessary to enhance the catalytic activity of the contact masses. Local chemical analysis by scanning electron microscopy has established the ratio of the particle size of the initial polycrystals of copper chloride(I) and the resulting copper particles as a result of reduction on silicon. The process of deep reduction makes it possible to obtain particles up to 5 microns in size. These results provide useful insights into the formulation of coatings containing organosilicon compounds to reduce friction in hydrocarbon transport.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медь</kwd><kwd>кремний</kwd><kwd>контактная масса</kwd><kwd>катализ</kwd><kwd>дисперсность</kwd><kwd>восстановление</kwd><kwd>металлография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper</kwd><kwd>silicon</kwd><kwd>contact mass</kwd><kwd>catalysis</kwd><kwd>dispersion</kwd><kwd>reduction</kwd><kwd>metallography</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">Jones, R.
