Electrical properties of the glasses in the system (CuI,CuCl)-Cu 2O-MoO3

Copper-ion conducting glasses were prepared in the system (CuI,CuCl)-Cu₂O-MoO₃ using a rapid quenching technique. These glasses have high ionic conductivities at room temperature in the range of 10^-4 to 10^-2 S-m^-1, and the conductivities increase with increasing CuI content but decrease with increasing CuCl content. The increase in the conductivity can be explained in terms of a decrease in the activation energy for conduction, and the activation energies for conduction are 0.19-0.39 eV. The electronic conductivities were measured by the Wagner polarization method. The ion transport numbers are 0.995-0.997, and it is shown that the transport number of Cu⁺ ions in these glasses is practically unity. The dielectric relaxation time is in the range of 3.7×10^-4 to 1.2×10^-3 s. The activation energies for ion jumping are 0.18-0.36 eV, and these are similar to those for conduction
