摘要: Abstract Mixing enthalpy in LnX3–MX liquid systems (M = alkali metal, X = halide) has been analysed. This is negative all systems. The maximum of the absolute value molar mixing depends on ionic radius lanthanide(III) and alkali metal cations as well halide anion. smaller Ln3+, larger enthalpy. increases also with cation. Finally it decreases increase common results measurements are compared electrical conductivity mixtures discussed terms complex formation these melts. All experimental concerning both LnX3 binary (temperatures enthalpies phase transitions, heat capacity, diagrams) subsequently used an optimization procedure order to obtain self-consistent sets thermodynamic data characterizing TbBr3–KBr system reported example.
