Abstract. Phosphate glasses of the compositions 20Li2O-(50-x)Li2WO4-xTiO2-30P2O5 (0≤x≤15, mol%) were prepared by the melt quenching method. The amorphous nature of these glasses was confirmed by the XRD diffraction. Their characteristic temperatures were determined by DSC analysis. Impedance spectroscopy is used to determine their electrical conductivity as a function of temperature. The obtained results show that the conductivity as a function of temperature follows an Arrhenius-law.
