DC conductivity, density and infrared investigations have been carried out on ZnO-PbO-B2O3 glasses. The activation energy for conduction shows a maximum value at a specific ZnO concentration, depending on the glass composition. Both the conductivity and the density increase with an increase in the oxygen to boron ratio in a common dependence regardless of glass composition. The molar volume decreases with increasing ZnO for all compositions. The results are discussed considering the dual role of ZnO and its effect on glass structure.
