Abstract: The glasses 60B2O3 -(40-x) PbO-xMCl 2 and 50B2O3 -(50-x)PbO – xMCl2 (M = Pb, Cd) containing different concentrations of PbCl2 and CdCl2 were prepared. The ionic transference number of the glass samples was determined using dc polarization technique. The ionic transference number obtained is nearly 1 indicating that the electrical conduction in the glass samples is purely ionic. The dependence of ac conductivity and dielectric constant on temperature and frequency was investigated and the electrical moduli were analyzed. The variation of dielectric constant and ac conductivity with increase in mole percentage of PbCl2 or CdCl2 has been investigated on the basis of structural changes occurring in the glass samples.
