Na-Ti-Si氧化物Ti元素的化学状态分析

利用熔融方法制备了Na2O-TiO2-SiO2系统玻璃样品，用IR以及XPS等测试手段对系统玻璃样品结构进行了分析。结果表明：Na2O-SiO2-SiO2系统玻璃中Ti^4 离子可以部分地取代Si^4 离子的位置而以网络形成体的形式参与成玻。此外，通过对该系统玻璃的XPS钛元素的化学状态分析，认为该系统玻璃中Ti^4 离子存在TiO4],TiO6]等几种不同的微结构单元，并且随着玻璃中TiO2含量的增加，该系统玻璃中四方双锥结构的TiO6]与正四面体结构的TiO4]之比增大。

Study on the Microstructure of Na2O-TiO2-SiO2 Glass

Na 2O-TiO 2-SiO 2 glass samples have been prepared by melting methods. Measurements such as Infrared spectroscopy(IR) and X-ray photoelectron spectroscopy(XPS) have been carried out. It is found that Ti 4+ may take place of the Si 4+ to become glass network former. Furthermore, in the glass system a few different microsturctural units such as TiO 4],TiO 6] and so on have existed. Finally the ratio of the microsturctural unit TiO 6] to TiO 4] increases with the increasing of TiO 2 content.
