摘要
实验室制备高铝硅酸盐玻璃,利用红外光谱、拉曼光谱对玻璃结构进行表征。结果表明样品玻璃的骨架主要由硅氧四面体[Si O4]连接而成。铝氧四面体[Al O4]也参与成网,与[Si O4]相连使断网变得完整。铝氧八面体[Al O6]与其他离子或基团处于网络空隙里,作为网络外体游离在网络之间。随着样品中Al2O3含量的增多,玻璃中桥氧的数目在增加,非桥氧的数目在减少。
In order to investigate the structure of high-alumina silicate glass, infrared spectroscopy, raman spectroscopy were used to test the glass samples. The high-alumina silicate glass samples were prepared in the laboratory. The results showed that the main network structure of high-alumina silicate are constituted of [ SiO4 ], [ AlO6 ] and other ions or groups in the gaps of the network are foreign body between networks, and the structure of [ AlO4 ] is similar with the structure of [ SiO4 ], so [ AlO4 ] can connect to [ SiO4 ] and play a role in network structure of the glass just as the [ SiO4 ]. With the content of Al2O3 in high-alumina silicate glass increasing, the content of bridging oxygen increase, and the content of non-bridging oxygen decrease.
