Abstract:
Phase equilibrium in the DyBr3-KBr binary system (Fig. 1) was established by Differential Scanning Calorimetry (DSC). The phase diagram exhibits two eutectics and two stoichiometric compounds. The first compound, K3DyBr6, undergoes a solid-solid phase transition at 694 K and melts congruently at 991 K. The second one, K2DyBr5, melts incongruently at 733 K. The compositions of KBr-K3DyBr6 and K2DyBr5-DyBr3 eutectic mixtures were determined by the Tamman method as x(DyBr3) = 0.159 (886 K) and 0.454 (689 K), respectively. The electrical conductivity of the DyBr3-KBr liquid mixtures, together with that of pure components was measured down to temperatures below solidification. Results obtained are discussed in terms of possible complex formation.
