摘要
对CsBr-NdBr3-13%HBr-H2O四元体系25℃时的相平衡进行了研究,比较CsBr与REBr3(RE=La,Pr,Nd,Sm)在氢溴酸介质中反应的相化学关系发现,轻稀土的相似性和以Nd为界的"二分组效应"首次在相化学行为上有所体现.对化合物5CsBr·2REBr3·22H2O做了热分析测试.根据体系的相化学关系设计了新的固相反应,并进行了新类型化合物的合成.
Phase chemistry of CsBr-NdBr3-13%HBr──H2O quaternary system at 25℃ wasstudied. The characteristics of the light rare earth compounds is very similar and the'bicomponent effect' of the light rare earth is very obvious by comparing the phase chemicalbehavior and the relation of these quaternary systems with each other. Meanwhile, a new solidreaction is designed according to the phase relation and new compounds are synthesizedaccording to the design.
