      <abstract xml:lang="ru">
        <p>Проведено термодинамическое моделирование восстановления дихлорида меди в атмосфере различных газообразных гидридов (в аммиаке, моносилане, метане) в температурном интервале 273-1000 К. Расчеты показывают, что в более узких диапазонах значений температуры, отвечающих протеканию реакций твердотельного гидридного синтеза (ТГС) металлических веществ, образование металла, как правило, подтверждается теорией. В результате термодинамического моделирования получен принципиальный результат о подавлении конкурирующих процессов нитридирования, силицирования и карбидизации металла в условиях ТГС, имеющий значение для металлургических производств. Это дополнительно обосновывает корректность предыдущих экспериментальных исследований разработчиков ТГС металлов с модифицированной поверхностью и улучшенными свойствами. Путем моделирования выявлено, что восстановление твердого дихлорида меди до металла в атмосфере аммиака или метана происходит ступенчато (последовательно, согласно правилу Байкова) через промежуточные стадии образования соединения низковалентной меди – хлорида меди (I).</p>

        <p>Thermodynamic modeling of the reduction of copper dichloride in the media of various gaseous hydrides (ammonia, monosilane, methane) in the temperature range 273-1000 K was carried out. Calculations show that in narrower temperature ranges corresponding to the reactions of solid-state hydride synthesis (SHS) of metal sub- stances metal formation is usually supported by theoretical propositions. As a result of thermodynamic modeling, a principal result was obtained on the suppression of competing processes of nitriding, siliconizing and carbonization of metal under SHS conditions, which is important for metallurgical production. This additionally substantiates the correctness of previous experimental studies of SHS metals with modified surface and improved properties. By mod- eling, it was found that the reduction of solid copper dichloride to metal in ammonia or methane occurs stepwise (se- quentially, according to the Baykov rule) through the intermediate stages of the formation of a compound of low- valent copper – copper (I)chloride.</p>
