IR, WAXS and EXAFS arn used to study the structure of the non-crystalline io nic conductors in the Li2O-Nb2O5-SiO2 system. From the analysis, it is known that Nb5+ ions exist mainly as (NbO6) in the non-crystalline network.

• 本文采用红外吸收光谱法、X射线散射法和EXAFS方法研究了LiO-Nb_2O-SiO_2系统非晶态离子导体的结构,认为Nb~(5+)在非晶结构网络中主要是以[NbO_6]形式存在。
