摘要: 用11B连续波核磁共振谱研究了锂硼钒酸盐玻璃的结构,测量了BO4,BO3s和BO3A各结构单元的比例。实验表明,锂硼钒酸盐玻璃中N4的最大值近似为一常数,与V2O5的含量无关。Li2O被V2O5和B2O3分享。并推测V2O<

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.
