IR spectroscopy, measurement of Tg and calculation of the molar volume were used as a basis for assessing the structural conditions in glasses of the system Li₂Cl₂-Li₂O-B₂O₃. Li₂O and Li₂Cl₂ have different functions in the structure of glasses. Li₂O enters the structure of the B-0 skeleton as a modifier, whereas Li₂Cl₂ does not take part in modification of the basic skeleton of glasses. Observation of the fracture areas by a scanning electron microscope revealed the presence of metastable separation in the glasses in question. |
