Abstract
Borophosphate glasses with dopants SrO and Li2O in the composition of 20(B2O3) + 30(P2O5) + (50-x) (SrO) + x (Li2O) where x = 10, 20, 30, 40 and 50 were synthesized by standard melt quenching technique. All the glass samples were annealed to extract the thermal strains presence in it if any, its amorphous nature was evidenced by XRD characterization, density of the as synthesized glass series has been calculated at the ambient temperature using Archimedes’ principle and also its molar volume was estimated. With increase in mole fraction of Li2O, density of the glass samples found deceasing and the molar volume observed to be increasing as per the trends. Using Nernst-Einstein equation, high temperature dc activation energy has been calculated.
