Abstract

Abstract A series of five samples of Borophosphate glasses doped with SrO and Li2O within the composition of 20(B2O3) + 30(P2O5) + x (SrO) + (50-x) (Li2O) where x = 10, 20, 30, 40 & 50. The Glass Samples were prepared by the melt quenching technique, and the samples were annealed to remove if any thermal strains present. Glasses were characterized by DSC studies in the temperature ranges from 423-673K to determine the glass transition temperature (Tg). Here Tg increases linearly with SrO mole fractions, the FTIR study shows the existence of different structural and functional group of B2O3, P2O5 such as BPO4, BO3 and BO4 units in the network. Borophosphate glasses containing SrO and Li2O, which exhibits different IR bands, related to SrO structural units.
