Abstract

Методами физико-химического анализа – дифференциально-термическим, высокотемпературным дифференциально-термическим, рентгенофазовым, микроструктурным, а также измерением микротвердости изучена система Sm2Te3–GeTe, которая является квазибинарным сечением тройной системы Ge–Sm–Te. При соотношении исходных теллуридов 1:1 (50 мол. %) и температуре 1100 К по перитектической реакции ж+Sm2Te3→ GeSm2Te4 образуется тройное соединение GeSm2Te4. Образцы системы, богатые GeTe, представляют собой компактные слитки блестяще-серого цвета, а сплавы, бо-гатые Sm2Te3 – спек черного цвета. Ликвидус системы Sm2Te3–GeTe состоит из трех ветвей: Sm2Te3, GeSm2Te4 и a-твердых растворов на основе GeTe. Рентгенофазовый анализ закристаллизованных образцов показал, что набор рентгеновских отражений соответствует фазам Sm2Te3, GeSm2Te4 и a-твердых растворов на основе GeTe. Установлено образование инконгруэнтно плавящегося соединения состава GeSm2Te4, которое может использоваться как термоэлектрический материал.

Sm2Te3 - GeTe相平衡

物理化学分析——热、热、x射线、微硬度和微硬度测量——研究了Sm2Te3 - GeTe系统，这是三重通用- Sm - Te的准二进制截面。在1比1 (50 mos)中，最初的特鲁里德数。1100 k是由j +Sm2Te3 GeSm2Te4形成的三重化合物GeSm2Te4。系统的样品，丰富的GeTe，是一种精细的灰色金条，而合金，Sm2Te3是黑色的。Sm2Te3 - GeTe由三个分支组成:Sm2Te3、GeSm2Te4和a-固体溶液。结晶样品的x射线分析显示，x射线反射与Sm2Te3、GeSm2Te4和a-固体溶液相匹配。在GeSm2Te4中发现了一种完全融化的化合物，可以用作热电材料。= =结构= = GeTe形成了一个狭窄的固体溶液区域，由REFERENCES Kohri H、Shiota、Kato M和Ohsugi J组成。科学和技术进步，2006年，v46, pp, 168-173。https://doi.org/10.4028/www.scientifi c.net/ST.46.168 Gelbstein Y。B Dado, Ben - Yehuda O Sadia Y。Dashevsky z and Dariel m . p .
