Structural interpretation of concentration dependences of molar volume of three-component alumosilicate glass containing oxides of the first and second groups

The nature of the concentration dependence of the molar volume of three-component aluminosilicate glasses, in which the content of R ₂ O (or RO) exceeds the content of Al ₂ O ₃ , is determined by the degree of depolymerization structural glass mesh. In glasses with an equimolar content of R ₂ O (or RO) and Al ₂ O ₃ , the molar volume is additive and depends on the partial values ??of the molar volume of "silica "and" aluminate "constituents of the structural grid.
