Ряд особенностей системы Cu—Se, а именно: наличие фазового превращения в соединении Cu2Se, высокая скорость диффузии ионов Cu, высокая упругость паров Se при повышенных температурах делают актуальным проведение комплекса экспериментальных исследований по разработке и оптимизации методологии получения объемного материала на основе селенида меди. Исследовано влияние режимов механохимического синтеза и способа последующего компактирования на термоэлектрические свойства и структуру селенида меди. Исходный материал получен методом механохимического синтеза, объемные образцы — методами горячего прессования и искрового плазменного спекания. Структура и фазовый состав исследованы методами рентгеновской дифрактометрии и сканирующей электронной микроскопии. Показано, что увеличение времени механосинтеза до 5 ч приводит к обеднению порошков медью и образованию нестехиометрической β−фазы Cu1,83Se, которая сохраняется и после искрового плазменного спекания. Сравнение структуры и свойств материалов, полученных методом искрового плазменного спекания и горячим прессованием, показало, что материал, изготовленный методом горячего прессования, обладает большей степенью дефектности зерен. Наибольшей термоэлектрической эффективностью ZT = 1,8 при температуре 600 °С обладает материал, полученный искровым плазменным спеканием. Показано, что основным фактором, влияющим на значение термоэлектрической эффективности ZT исследуемых материалов, является низкая теплопроводность. Разница в значениях теплопроводности у материалов, полученных разными методами, связана с электронной составляющей теплопроводности.</p></abstract><trans-abstract xml:lang="en"><p>Copper selenide is a promising material for power generation in medium−temperature range 600—1000 K. A number of features of the Cu—Se system, i.e. the existence of a phase transition in Cu2Se compound, the high speed of Cu ion diffusion and the high vapor pressure of Se at high temperatures, necessitate massive experimental investigations aimed to develop and optimize a method for obtaining a copper selenide base bulk material. In this work the effect of mechanochemical synthesis mode and subsequent compaction method on the thermoelectric properties and structure of copper selenide were studied. The source material was obtained by mechanochemical synthesis. The hot pressing and spark plasma sintering methods were used for obtaining the bulk samples. The structure and phase composition were studied by X−ray diffraction and scanning electron microscopy. We show that increasing the time of mechanochemical synthesis to 5 hours leads to copper depletion of the powders and the formation of nonstoichiometric phase Cu1,83Se which persists after spark plasma sintering. Comparison of the structure and properties of the material obtained by spark plasma sintering and hot pressing showed that the material obtained by hot pressing has a greater degree of the grain defects. The highest thermoelectric efficiency ZT = 1.8 at 600 °C was observed in the material obtained by spark plasma sintering. We show that the main factor affecting the value of the thermoelectric efficiency ZT of the studied materials is the low thermal conductivity. The difference in thethermal conductivities of the materials obtained by different methods is attributed to the electronic component of thermal conductivity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>термоэлектрический материал</kwd><kwd>селенид меди</kwd><kwd>механохимический синтез</kwd><kwd>искровое плазменное спекание</kwd><kwd>горячее прессование</kwd><kwd>нанокомпозитные материалы</kwd><kwd>термоэлектрические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermoelectric material</kwd><kwd>copper selenide</kwd><kwd>mechanochemical synthesis</kwd><kwd>spark plasma sintering</kwd><kwd>hot pressing</kwd><kwd>nanocomposite materials</kwd><kwd>thermoelectric properties</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">Snyder, G.
