【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,BO_3s和BO_3A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V₂O₅与B₂O₃可能结合生成(BV_4.5基团。更多还原

【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 LiaO with B₂O₃, and combined with B₂O₃ in the form BVO_4.5. 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.更多还原
