Thermodynamic and transport properties of the PrBr 3–MBr binary systems (M = Li, Na)

Abstract

DSC was used to investigate phase equilibrium in the PrBr 3–MBr (M = Li, Na) systems. They represent typical examples of simple eutectic systems. The eutectic composition and eutectic temperature, x(PrBr 3) = 0.265, T eut = 689 K and x(PrBr 3) = 0.409, and T eut = 658 K, where x(PrBr 3) denotes the molar fraction of PrBr 3, were found for PrBr 3–LiBr and PrBr 3–NaBr systems, respectively. The electrical conductivity of PrBr 3–MBr 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.
