The glasses of the type (30 一 x)Li2O 一 xK2O 一 10CdO 一 59B2O3 doped with 1 mol% of Fe2O3 were prepared by melt quench technique and their non-crystallinility has been established by XRD studies. The glasses were investigated for room temperature density and electrical conductivity in the temperature range 300 - 523 K and in the frequency range 102 to 105 Hz. The frequency and temperature dependence of conductivity as dielectric constant are presented.
