The thermal properties of a series of synthesized rubidium and cesium borosilicate glasses have been studied by differential scanning calorimetry. The values ??of the glass transition and crystallization temperatures have been determined, and the change in the specific heat of these glasses at the glass transition temperature has been determined. The thermal study data are compared with the results of the study of structural features by IR spectroscopy. The information obtained makes it possible to adjust the parameters of the heat treatment of glass-containing materials depending on their composition, which is important for improving the matrix glassy materials used in the immobilization of radioactive waste.
