Abstract

The measurements of electronic and ionic conductions in liquid In-Se and Cu-Se systems have been carried out separately as a function of concentration and temperature. The electronic conductivities of these systems have minima near the composition x = 0.58 for the In1-xSex system and x = 0.33 for the Cu1-xSex system. Both systems have maxima in the ionic conductivities at the same composition. In proportion as the electronic conductivity increases with changing composition, the ionic conductivity decreases. In Se-rich region of Cu-Se system, the change from negative to positive temperature dependence of the electronic conductivity and a discontinuous change in the ionic conductivity have been observed at a certain temperature.
