Structural interpretation of the concentration dependence of the molar volume of lead silicate glass

It was found that the nature of the concentration dependence of the molar volume of two-component lead-silicate glasses, as well as three-component lead-silicate glasses containing modifier oxides of the first and second groups of the periodic system, is due to the degree of depolymerization of the structural network. The molar volume of the structural network of the considered glasses is additive and is determined by the partial values ??of the molar volumes of its "silica" and "plumbate" components.
