Electrical conductivity of the molten EuBr2-MBr binary mixtures (MÂ =Â Li, Na, K, Rb, or Cs)

The electrical conductivity of all EuBr2-alkali metal bromide liquid mixtures was measured as function of temperature over the whole composition range. The activation energy, EA, was evaluated for all liquid mixtures. It was revealed that the classical Arrhenius dependence did not stand for any individual mixture. The obtained results were discussed in terms of complex formation in the melts.
