Phase diagram and electrical conductivity of the EuBr2–NaBr binary system

DSC was used to study phase equilibrium in the EuBr2–NaBr system. It represents a typical example of simple eutectic system with the eutectic composition, x(EuBr2) = 0.546, and eutectic temperature 762 K. The electrical conductivity of EuBr2–NaBr liquid mixtures was measured down to temperatures of solidification. Reflectance spectra of the pure components and their solid mixtures (after homogenisation in the liquid state) with different composition were recorded in order to confirm the reliability of the constructed phase diagram.
