Abstract

Phase equilibrium in the CeBr3–CsBr binary system was established from differential scanning calorimetry (DSC). This system includes three compounds, namely Cs3CeBr6, Cs2CeBr5 and CsCe2Br7; and three eutectics located at CeBr3 molar fraction x = 0.125; 0.459 and 0.700, respectively. Cs3CeBr6 undergoes a solid–solid phase transition at 712 K and melts congruently at 1034 K. Cs2CeBr5 decomposes in the solid state into Cs3CeBr6 and CsCe2Br7 at 685 K. The third compound, CsCe2Br7, melts congruently at 877 K. The electrical conductivity of CeBr3–CsBr liquid mixtures was measured down to temperatures below solidification over the whole composition range. Results obtained are discussed in term of possible complex formation.
