摘要: 运用DTA差热分析法和X射线衍射粉末法研究了Sml2-KI二元体系等压相图及该体系中KSm2Is,K2SmI4的性质和结构.借助J.Kutscher讨论REX3-AX(RE=稀土,A=碱金属)体系形成化合物规律的方法,对SmI2-AI,YbI2-AI(A=Na,K,Rb,Cs)两个系列形成的规律进行了初步讨论。

关键词: 相图, SmI2-KI体系, REI2-AI体系

Abstract: The isopiestic phase diagram of SmI2-KIbinary system, the properties and structures of KSm2I5, K2SmI4in the system were studied by DTA and X-ray powder diffraction methods. According to J. Kutscher's view point for discussing REX3-AX(RE=Rare earth metals, A=alkali metals), the formation rules of compounds in the SmI2-KI and YbI2-KI(A=Na, K, Rb, Cs)systems are discussed.

Key words: Phase diagram, SmI2-KI system, REI2-AI system
