摘要：

Germanosilicate glasses of compositions (mol%): (100 - x)(33Na(2)O center dot 67SiO(2)) center dot xGeO(2); where x = 20, 25, 30, 35 and 40 were studied using Raman and IR spectroscopy. Structural units existing in glasses were determined. The transition of silicon-containing anionic sheet structures to three-dimensional network with the formation of Si-O-Si bridge atoms was observed when germanium oxide was added to sodium disilicate.
