Structural analysis of 15Bi 2 O 3 -(50-x)PbO-35B 2 O 3 -xLi 2 CO 3 , x = 0,5,10,15 and 20) of lithium doped bismuth lead borate glass system (BPBL) using density, molar volume, and IR absorption spectra has been carried out for These glasses were prepared by the most reliable conventional melt quenching technique. Densities and molar volumes have been measured as a function of Li 2 CO 3 content. Almost linear variation in the density and the molar volume has been observed in the present glasses and is attributed to the role of Li+ in these glasses. IR spectra of these glasses exhibit characteristic vibrations due to the borate network. The band at 400 cm −1 -600 cm −1 due to absorption refers to metallic and cationic vibrations of metallic cations of Bi 3+ and Li + .
