Плотность полученных ТЭМ составила 97–98% от плотности синтезированных материалов. Установлено, что термический коэффициент линейного расширения (ТКЛР) PbTe с ростом температуры увеличивается с 20.14 × 10<sup>–6</sup> К<sup>–1</sup> при 550 К до 23.07 × 10<sup>–6</sup> К<sup>–1</sup> при 900 К. ТКЛР GeTe с ростом температуры падает от 13.94 × 10<sup>–6</sup> К<sup>–1</sup> при 550 К до 11.93 × 10<sup>–6</sup> К<sup>–1</sup> при 675 К, затем растет до 24.47 × 10<sup>–6</sup> К<sup>–1</sup> при 900 К. Проведено сравнение ТКЛР наноструктурированных материалов и материалов, полученных традиционными методами. При температурах от 300 до 750 К значения ТКЛР PbTe и GeTe различаются на 15–40%, что может приводить к разрушению термоэлементов.</p></abstract><trans-abstract xml:lang="en"><p/></trans-abstract><kwd-group xml:lang="ru"><kwd>термоэлементы</kwd><kwd>наноструктурирование</kwd><kwd>термоэлектрические материалы</kwd><kwd>термическое расширение</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>24-19-00158</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shi X.L., Zou J., Chen Z.G.
