摘要
用红外吸收光谱系统研究了含钛钡硼硅酸盐玻璃的结构．结果表明：ＴｉＯ２含量较低时Ｔｉ４＋主要处于［ＴｉＯ４］中．当ＴｉＯ２摩尔含量约为２０％时，有少量［ＴｉＯ６］形成．在本文所研究的钛钡硼硅酸盐玻璃组成范围内，当玻璃中Ｔｉ４＋和Ｂ３＋共存时，Ｂ２Ｏ３含量的变化不会改变Ｔｉ４＋的结构状态，但ＴｉＯ２的存在将促使部分［ＢＯ４］转化成［ＢＯ３］．将这一现象称为“钛硼结构效应”
The structure of barium borosilicate glasses containing titanium is studied systematically by infrared absorption spectra.The result shows:the Ti 4+ is mainly in the tetrahedra when the content of TiO 2 is lower,and a small amount of octahedra is formed when the mole content of TiO 2 is about 20%.When Ti 4+ and B 3+ co exist in these glasses,the structure state of Ti 4+ will not alter with the change of B 2O 3 content;however the existence of TiO 2 will impel a part of B 3+ to transform from terahedrs into triangles.The latter phenomenon is called “The Titanium Boron Structural Interaction Effect”.
