The electrical properties of multi-component fluoride glasses which were based upon ZnF2 were studied by using complex impedance techniques at frequencies ranging from 5Hz to 500kHz. It was found that the conductivity of ZnF2-19.5BaF2-10InF3-10SrF2-10LiF-0.5NdF3 was equal to 4.89 x 10-8S/cm at 400K, and that the overall data could be described by:

σT (SK/cm) = 4.17 x 105 exp[-0.82(eV)/kT]
