Abstract

In this work, we used cooling to experimentally determine the temperature dependence of the specific heat capacity of glass made with the compound 2B2O3 + Bi2O3 (2:1) with the addition of 0,01, 0,02, 0,04, 0,08, 0,12, and 0,5 mol NaOH to 1 mol of the initial mixture. It has been experimentally determined that with an increase in the Na content in the initial mixture, the temperature dependences of the specific heat capacity of glasses from the melt to close to room temperature are complex. Their physical interpretation is given based on the features of molecular mobility in the temperature range up to and above the glass transition temperatures.
