The conductivity was measured by the complex impedance method over the frequency range of 100 Hz to 20 kHz. Compared to Cu₂O, Cu₂I₂ has a more distinct effect on the level of conductivity. The conductivity of the glasses increrased with increasing Cu₂I₂ content and the opposite relationship was observed with increasing O/P ratio. The maximum conductivity was with a glass having the lowest concentration of conductive Cu⁺ ions, and the glass exhibited the largest molar volume. This fact indicates that electrical conductivity of glasses is not only a function of the concentration of conductive ions, as a significant part is also played by migration of ions which is given by the molar volume of the glass.
