Transport Properties of EuCl2 and Phase Equilibria in LiCl-EuCl2 System

Abstract

The ionic conductivity of EuCl2 was investigated at high temperatures, including the melting point. Measurements were performed on polycrystalline specimens obtained by the solidification of the corresponding melt. The behavior of the conductivity and the apparent Arrhenius activation energy was characterized. It is suggested that the conductivity behavior results from anion sublattice disordering within the crystals up to the melting point. The variation in transport properties correlates well with the crystal structure of EuCl2. The phase diagram of the LiCl–EuCl2 binary system was constructed based on DSC measurements. This system was found to be a simple eutectic type featuring the incongruently melting compound LiEu3Cl7. The CALPHAD method was employed for thermodynamic modeling, incorporating both experimental and literature data for the LiCl–EuCl2 system.
