Abstract

Dynamic Raman spectra of sodium borosilicate glasses containing largeamounts of boron oxide have been studied as functions of temperature andholding time. Such characterization enabled measuring the changes in thenature and states of the molecular species that were present in the glassesand their Melts. The data indicate that boroxol rings involving one or morefour-coordinated boron ions in the sodium oxide-containing glasses decreasedin concentration as they were heated through melt temperatures as was notedearlier for boroxol groups involving three-coordinated boron ions in pureborosilicate compositions.
