The current study analyzes the influence of Na2O on the physical and structural properties of lead silicate glasses synthesized by melt-quench technique. The non-crystalline nature of the prepared glass series isvalidated by a noticeable hump in X-ray diffraction spectra. With the rise in Na2O content, the density of samples decreases linearly from 5.309 to 3.292 (g/cm3) and hence molar volume increases. The diminishing trend of oxygen packing density (OPD) with rising Na2O content implies a weakening of the oxide network. The structural analysis is performed using Fourier transform infrared (FTIR) spectroscopy which revealed several key structural features of the glass network. PbO is mainly composed of PbO3 and PbO4 structural units. Sodium oxide exists as network modifier, which disrupts the silicon-oxygen network of SiO2. SiO4 units are formed along with asymmetric stretching vibration of Si-O-Si in SiO4 tetrahedra containing two non-bridging oxygen atoms per silicon (Q2 species) and Si-O bond in polymerizedSiO4 tetrahedra (Q4 species).
