Raman spectroscopy of borosilicate and germanate-silicate glasses and melts

33 mol % Na 2 O · 67 mol % SiO 2 + x B 2 O 3 (GeO 2 ) glasses and melts with x = 0 and 20 mol % are studied by high-temperature Raman spectroscopy. The laws of formation of the anion structure of glasses and melts of borosilicate and germanate-silicate systems are shown to be different. The dominant...

Description
Summary:33 mol % Na 2 O · 67 mol % SiO 2 + x B 2 O 3 (GeO 2 ) glasses and melts with x = 0 and 20 mol % are studied by high-temperature Raman spectroscopy. The laws of formation of the anion structure of glasses and melts of borosilicate and germanate-silicate systems are shown to be different. The dominant anion groups in the systems are identified, and the structural changes occurring with increasing temperature and during a glass-melt transition are detected.
