Abstract
The effect of additions of calcium, barium, and strontium oxides on the thermal properties of sodium fluorosilicate glasses was studied by means of differential scanning calorimetry. The data obtained from the thermal studies are compared with the results of structural studies of these glasses, and the factors determining the observed change of vitrification temperature and specific heat are established. The obtained results make it possible to adjust the parameters of synthesis and heat treatment of matrix glass-containing borosilicate materials used for immobilization of radioactive waste.
