Abstract

Nuclear magnetic resonance (NMR) studies of the structure of glasses have been carried out at Brown University for some twenty years(1–24). Much of the work has involved the use of B11 NMR spectra to identify BO3 and BO4 units in binary borate glasses and to determine quantitatively the fraction N4 of four-coordinated boron in the glasses. Recent work has extended the systems to silicate glasses, ternary systems, oxygen bonding in glasses, and the identification in borate glasses of the large structural groupings found in the crystalline borate compounds. The studies of borate glasses lend strong support to the model of borate glasses proposed by Jan Krogh-Moe(25). These recent developments in NMR studies of borate glasses are summarized in this paper after presentation of some basic NMR theory.
