The aim of this work is to convert into harmless reusable materials industrial wastes already produced and accumulated from a lead battery plant. Slag, containing 5-20 wt% lead resulting from the thermal recycling of lead from spent batteries, was vitrified with the necessary amount of silica and other additives in order to obtain glasses with desired chemical stability. The most convenient glass was selected and then manufactured and characterised. The influence of composition and temperature on the glass structure and properties were followed using infrared reflectance spectroscopy up the the glass transition temperature, Tg, and electrical conductivity experiments in the solid and molten states. The results were correlated with data obtained from magic-angle spinning nuclear magnetic resonance, ultraviolet-visible spectra and thermal analysis data.
