Abstract

Abstract: Phase chemistry of CsBr-NdBr₃-13%HBr──H₂Oquaternary 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.

Key words: Quaternary system, Light rare earth tribromide, Reaction design and synthesis, Cesium bromide, Bicomponent effect
