Zusammenfassung:	Phase equilibrium in the CeBr3-RbBr binary system was established from differential scanning calorimetry (DSC). This system has three compounds Rb3CeBr6, Rb2CeBr5 and RbCe2Br7 and two eutectics located at (x=0.141; 858K) and (x=0.528; 762K), respectively. Rb3CeBr6 forms at 614K, undergoes a solid-solid phase transition at 695K and melts congruently at 966K. Rb2CeBr5 melts incongruently at 830K and RbCe2Br7 at 741K. The electrical conductivity of CeBr3-RbBr liquid mixtures was measured down to temperatures below solidification over the whole composition range. Results obtained are discussed in term of possible complex formation.
