Результаты рентгеноструктурного анализа сплавов подтвердили образование в системе непрерывного ряда твердых растворов со структурой никель- арсенидного типа. Постоянные а исходных соединений CoSb и CoTe близки по величинам, что определяет практически параллельный оси концентрации ход зависимости a = f(x). Зависимость постоянной с от концентрации плавно возрастает от 5,181 Å у CoSb до 5,371 Å у CoTe с небольшим прогибом к оси концентраций. Плотность сплавов, определенная методом гидростатического взвешивания в тетрахлориде углерода, имеет линейный характер зависимости от концентрации. Концентрационная зависимость микротвердости сплавов системы CoSb1–x Tex проходит через слабо выраженный максимум в области средних составов. Пондеромоторным методом в магнитном поле 6,8 · 105 А/м в интервале температур 80–1200 К измерены удельная намагниченность и магнитная восприимчивость сплавов системы. При температуре жидкого азота величина удельной намагниченности максимальна (~6,0–6,5 Гс · см3 · г–1) у составов CoTe и CoSb0,1Te0,9 и практически равна нулю у CoSb и твердых растворов на его основе. Твердые растворы составов х = 0,4–0,9 обладают температурой магнитного перехода, превышающей 1200 К.</p></abstract><trans-abstract xml:lang="en"><p>By the method of melting special powder amounts of cobalt antimonide and cobalt telluride in vacuum, the solid solutions alloys of the CoSb1–x Tex system were synthesized with the NiAs structure. X-ray analysis results of the alloys confirmed the formation of a continuous series of solid solutions with a nickel-arsenide-type structure in the system. The constants a of the initial CoSb and CoTe compounds are close in values, which determines the course of the dependence a = f(x) that is practically parallel to the concentration axis. The dependence of the constant c on the concentration increases smoothly from 5.181 Å in CoSb to 5.371 Å in CoTe with a slight deflection to the concentration axis. The alloy density, determined by the hydrostatic weighing in carbon tetrachloride, has a linear dependence on the concentration. The concentration dependence of the micro hardness of the CoSb1–x Tex alloys passes through a weakly expressed maximum in the range of average compositions. Specific magnetization and magnetic susceptibility of the alloys are measured by the ponderomotive method in a magnetic field of 6.8 · 105 A/m in the temperature range 80–1200 K. At the temperature of liquid nitrogen, the value of specific magnetization is maximum (~6,0–6,5 Гс · см3 · г–1) in CoTe and solid solutions based on it. Solid solutions of compositions x = 0.4–0.9 have a magnetic transition temperature exceeding 1200 K. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>твердые растворы</kwd><kwd>структура</kwd><kwd>плотность сплавов</kwd><kwd>удельная намагниченность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solid solutions</kwd><kwd>structure</kwd><kwd>alloys density</kwd><kwd>specific magnetization</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">Маковецкий, Г.
