| Abstract: | The structure of lithium borovanadate (Li2O-B2O3-V2O5) glasses was studied by 11B CW-NMR technique. The fractions of BO4 and BO3 units were measured and analyzed. Basing on a FDB model, the structural model of lithium borovanadate glasses was proposed.We showed that V2O5 shared Li2O with B2O3, and combined with B2O3 in the form BVO4.5. The (N4)max are approximately constant with different K. According to this experimental result, it was deduced that there is no Reedmergnerite unit in lithium borovanadate glasses. We also learnt that without Li2O, V2O5 and B2O3 could not combine directly. |
