Abstract

The relation between change of the specific heat (ΔC p) accompanying the glass transformation and the chemical composition of glasses (Na2O, CaO, MgO)-Al2O3-SiO2 system has been studied. The exchange of modifiers in the glass structure causes the ΔC p increase in the sequence Na>Ca>Mg. Change the glass network composition by introducing Al into it makes smaller increase of the ΔC p values. It has been shown that degree of ΔC p value changes is dependent on the iconicity/covalence of chemical bonds of cations with oxygen of glass structure network.
