摘要: 利用11B的核磁共振谱研究了锂、硼、硅酸盐(Li2O·B2O3·SiO2)三元玻璃体系,测量并分析了BO4单元与对称和非对称的BO3单元的比例。分析结果表明,三元体系的结构单元亦可适用于锂、硼玻璃的二元体系的FDB模型说明,其差异在于前者中的Li2O由B2O3与SiO2按比例分享。

Abstract: 11B NMR studies have been carried out in the system of lithium borosilic-ate glasses Li2O-B2O3-SiO2 The fraction of BO4 and BO3 units was measured and analyzed according to a structural model.The results indicate that the ternary system can be explained by a modified FDB model. The difference between the binary and ternary system is the sharing of Li2O between borate and silica.
