Abstract: 10B NMR studies have been carried out on lithium borate glasses over the entire glass-forming region of the system. Using the ideas of Krogh-Moe, the relative abundances of the various structural groupings are inferred from the data by fitting computer-simulated lineshapes to the experimental spectra. Structural model are proposed which are consistent with the data: for 0.4 R < 1.0, where R = mol% Li2O/mol% B2O3, the model states that diborate and tetraborate units are proportionately destroyed to form metaborate units and loose BO4 units; for 1.0 < R < 1.86, the model states that metaborate units and loose BO4 units are destroyed linearly but not proportionately to form pyroborate and orthoborate units. These results are compared with earlier 11B NMR studies from this laboratory.
