Abstract
In this work, the temperature dependence of the specific heat capacity of glasses obtained on the basis of the Na2B4O7 + Bi2O3 compound with different concentrations of sodium tetraborate and bismuth oxide in the initial mixture was studied experimentally during cooling. It has been experimentally shown that with a change in the concentration of the initial substances, the specific heat capacity of the sample’s changes, and a shift of the maxima towards low temperatures is observed with an increase in the concentration of bismuth oxide. A physical interpretation of the nature of the maximum on the temperature dependence of the specific heat is given.
