In studies of the structure of three-component silicate glasses containing two alkali metals it must be taken into account that the heterogeneous structure of two-component sodium and lithium silicate glasses results from liquid-liquid phase separation [1–7] and that the immis- cibility region extends to an alkali oxide content of about 20 mole% in the first case and 33 mole% in the second. The problem of the structure of glasses of the type xNa2O · (1-x)R2O · ySiO2 can then be approached by elucidation of the influence of addition of various alkali oxides on phase separation in the sodium silicate system.
