| 摘 要： | 本文应用红外光谱和喇曼光谱分析技术，研究了Ｋ２Ｏ－Ｂ２Ｏ３－ＳｉＯ２系统玻璃的结构．结果表明，在ＳｉＯ２／Ｂ２Ｏ３＞２的情况下，无论Ｋ２Ｏ／Ｂ２Ｏ３＞１、≈１、还是＜１，玻璃结构中均存在［ＢＯ３］，Ｓｉ－Ｏ－－Ｏ－Ｓｉ－Ｏ－及各种硼酸盐基团，在实验组成范围内，玻璃结构以硅氧网络为主，硅氧网络和硼氧网络上均带有非桥氧，并且对这种结构特征产生的原因进行了分析．另外，实验结果还说明ＳｉＯ２／Ｂ２Ｏ３和Ｋ２Ｏ／Ｂ２Ｏ３是影响网络结构的主要原因．

| Abstract: | The infrared and Raman spectroscopic technique has been used to study the structure of K O-B O-SiO systema-glasses. The -results indicate that with SiO2/B2O3>2 theBO3]triangles,2 Si-O, O-Si-O and other borate groups are formed in the glasses regardless of K2O/B2O3>1,=for<1.There are NBO ions in both silicate-oxygen and borate-oxygen groups.The SiO2/B2O3 and K2O/B2O3 ratios could change the struture of the networks. Finally,the causesare discussed. |
