Abstract

Glasses in the system (PbO) 30(P 2O 5) 40(ZnO) 30-x(Li 2O) x (where x = 0, 15, 20, 25, 30 mol) and (PbO) 30(P 2O 5) 50(ZnO) 20-x(Li 2O) x (where x = 0, 5, 10, 15, 20 mol) were prepared by conventional melt quenching technique. XRD and DSC measurements were performed to confirm their amorphous nature. Thermal stability factor (S) has been evaluated using the values of T g and T c. The refractive indices of these glasses lie in the range of 1.40-1.45. IR spectra of these glasses show absorption peaks in the range 1233-1247 cm -1, 1076-1087 cm -1, 905-894 cm -1, 735-731 cm -1 and 531-556 cm -1 corresponding to PO, PO -, (POP) AS, (POP) S and OPO vibrations respectively. The peak corresponding to PO, shows red shift with increasing Li 2O content indicating depolymerization of phosphate network. © 2012 Elsevier B.V.
