Phase diagram and specific conductivity of the DyBr sub(3)-CsBr binary system

Phase equilibria in the DyBr sub(3)-CsBr binary system were established from differential scanning calorimetry (DSC) measurements. This system exhibits two compounds, namely Cs sub(3)DyBr sub(6) and Cs sub(3)Dy sub(2)Br sub(9), and two eutectics located at DyBr sub(3) molar fractions x = 0.102 (T =...

Description
Summary:Phase equilibria in the DyBr sub(3)-CsBr binary system were established from differential scanning calorimetry (DSC) measurements. This system exhibits two compounds, namely Cs sub(3)DyBr sub(6) and Cs sub(3)Dy sub(2)Br sub(9), and two eutectics located at DyBr sub(3) molar fractions x = 0.102 (T = 862 K) and x = 0.579 (T = 795 K), respectively. Cs sub(3)DyBr sub(6) undergoes a solid-solid phase transition at 724 K and melts congruently at 1086 K. Cs sub(3)Dy sub(2)Br sub(9) melts incongruently at 891 K. The specific conductivity of DyBr sub(3)-CsBr liquid mixtures was measured over the whole composition range. Results obtained are discussed in term of possible complex formation.
