外文摘要：© 2021Enthalpy increment data were acquired for borosilicate and doped borosilicate glasses containing oxides of uranium and surrogates of plutonium (CeO2, Nd2O3 and Gd2O3) using isoperibol drop calorimetry. The specific heat of borosilicate glasses were derived from these data and compared with doped glasses. The specific heat of the pristine glass is nearly similar to that of BSGU and found to show a dissimilar trend for BSGUCe and BSGRE. Internal network connectivity of the base glasses was investigated using micro-Raman spectrometer and compared with the glass containing high and low concentration of modifier (Na2O) for better understanding of thermal stability of the glasses. The Raman spectra reveal changes in the network structure with varying concentration of Na2O.
