摘要：

Phase equilibrium in the PrBr3-RbBr binary system was established by differential scanning calorimetry (DSC). This system, investigated for the first time, includes Rb3PrBr6, Rb2PrBr5 and RbPr2Br7 compounds, and three eutectics located at molar fraction of PrBr3 (x = 0.136: 865 K), (x = 0.488: 765 K) and (x = 0.679: 834 K), respectively Rb3PrBr6 undergoes a solid-solid phase transition at 704 K and melts congruently at 995K. Rb2PrBr5 melts incongruently at 803 K and finally RbPr2Br7 melts congruently at 852 K The electrical conductivity of PrBr3-RbBr liquid mixtures was measured over an extended temperature range down to temperatures below solidification and over the whole composition range. Results obtained are discussed in terms of possible complex formation (C) 2010 Elsevier B V All rights reserved.
