✦ Synopsis

The influence of the structure of the glass network as well as the influence of gradual substitution of CuI by CuCl in the systems (40 -n)CuI-KuCl-3OCu,O-3OP,O, (metaphosphate) and (40 -x)CuI-xCuCl-45Cu,O-15P,O, (orthophosphate), respectively, on the properties of Cuf-ion-conducting glasses were investigated. The glass formation was observed in the complete range of substitution of CuI by CuCl in both systems under study. The conductivities of the metaphosphate glasses reach orders of 1O-3 S cm-', the conductivities of orthophosphate glasses are one order of magnitude lower. Moreover, substitution of CuI by CuCl in the metaphosphate system causes a positive deviation of the conductivity from the additivity rule, with a maximum deviation for the molar ratio Cl/(Cl + I) = 0.750.
