| Abstract: | The experimental performance of the Shelyubskii method has been improved and applied to studying the change in glass homogeneity of the system Li2O-SiO2 caused by phase separation. Binodal temperatures obtained by this method are in good agreement with literature data obtained by an alternative method. The Shelyubskii method is capable of monitoring changes in glass homogeneity from a change in refractive index of the material with an accuracy of Δn×10?5. |
