Correlation of structural units and chemical stability in SiO2-PbO-Na2O ternary glasses: Spectroscopic methods

► Glasses in the ternary system SiO2-PbO-Na2O were studied. ► Structural units were investigated by Infrared, Raman and XPS spectroscopy. ► The chemical stability was determined by ICP-AES. ► The results were correlated to the role played by PbO in the structure.
