摘　　要：为了获得具有实用意义的非氟卤化物玻璃，有必要探索新的玻璃形成系统．本文获得了九个新的以ＰｂＸ_２（Ｘ：Ｉ；Ｂｒ，Ｃｌ）为基质的三元非氟卤化物玻璃形成系统，并且首次发现ＰｂＩ_２可以单独形成玻璃．所得的三元玻璃形成系统均表现出了良好的玻璃形成能力．此外，还从晶体结构、化学键的特性、离子半径及电负性等角度探讨了各卤化物在玻璃形成过程中所起的作用．结果表明，这些因素对玻璃形成均具有重要的作用．In order to obtain applicable non-fluoride halide glasses, it is necessary to find out new glass-forming systems. In this study, PbX_2 (X: I, Br, Cl)-based ternary glass-forming systems were obtained. It was found that the crystalline PhI2 could be vitrified without additives. All the systems have large glassforming regions. Besides, the functions of each component in the glass formation were discussed in the viewpoint of crystal structure, the characteristics of chemical bonds, ionic radius and electronegativity.The results showed that all such factors play important roles in the glass formation of a non-fluoride halide system.
