Abstract

Phase equilibrium in the PrBr3-CsBr binary system was established from Differential Scanning Calorimetry (DSC). This system has two compounds, Cs3PrBr6 and CsPr2Br7, and three eutectics located at molar fraction of PrBr3 (x = 0.108; 850 K), (x = 0.453; 767 K), and (x = 0.757, 870 K), respectively. Cs3PrBr6 undergoes a solid-solid phase transition at 726 K and melts congruently at 1051 K. CsPr2Br7 undergoes a solid-solid phase transition at 835 K, and melts congruently at 896 K. The electrical conductivity of PrBr3-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.
