摘要：

Raman spectra of 4 glasses in the system Li2O-SiO2 (41.3&leLi2O&le61.3mol%) prepared by rapid quenching were measured. The proportions of SiO4 units with 1, 2, 3 and 4 non-bridging oxygen per Si were determined from quantitative analysis of their Raman spectra. X-ray structural analysis of the glasses showed that the average atomic distance of the Si-O pair was elongated with increasing Li2O content due to weakening of the Si-O bond.
