摘    要:本文通过对11B核磁共振(11B-NMR)、红外光谱等实验方法,研究了LiF-LiCl-B2O3三元系统玻璃的结构和离子导电性,着重于F-离子在玻璃网络中所起的作用,以及F-,Cl-和Li+离子对导电率的影响。LiF-LiCl-B2O3三元系统玻璃,随LiF含量的增加,B由三角体向四面体变化,从而F-离子进入网络,使玻璃结构由B2O3]三角体层状结构向三维空间延展,形成了含有BO3F]基团的三维空间网络,Cl-离子以游离的离子存在于网络中,起着松散网络的作用,对提高电导率有利,而Li+离子作为传导离子,对电导率的贡献是主要的。本系统玻璃的电导率是随LiF,LiCl含量的增加而增大,在300℃时测得电导率σ=6.12×10-4Ω-1·cm-1关键词

Abstract:The structure and ionic conduction of glasses in system LiF-LiCI-B2O3, especially the role of F- ion in network of glasses and the influence of F-, Cl-, Li+ ions on conductivity have been studied by B-NMR and infrared spectra. For glasses in system LiF-LiCl-B2O3, the boron changes from triangular BO3] to tetrahedron BO3F] configuration with increasing LiF content, and F- ion participates in network formation. Therefore the network of glasees expands layer into space, and the glasses form three-dimensional network structure containing BO3F] unit. The Cl- ion exists in network in a state separated from network and plays the role of loosening network, so that it is effective for conductivity. The Li+ ion is the conductive phase, it gives the major contribution to conductivity. The ionic conductivity of glasses in this system increases with increasing LiF and LiCl content, and is 6.12×10-4Ω-1·cm-1 at 300℃.
