Structure of borate glasses by Raman spectroscopy
Conference

OSTI ID:6693833
Raman spectra of the alkali borate glasses are presented with emphasis on the implications of detailed frequency shifts and line shapes. The results are interpreted on a rather complicated three-level hierarchy of glass structures which include boron-oxygen polyhedra, topologically closed rings of polyhedra, and larger scale interconnected clusters of alkali-rich and alkali-poor structures. Both the model and the argument are deliberately vague. The borate glasses appear to be highly disordered materials with a size scale such that no presently available tool gives a really clear view of the structural detail.
