摘要
研究了文题玻璃的形成区并测定了它们的电导率、红外光谱、差热分析、离子迁移数和阻抗谱。结果表明:该玻璃只是F^-离子导电,其电导率随ZrF_4含量的减少而增加,当组成为65 ZrF_4-10 BaF_2-25 PbF_2时,在200℃时的电导率最高可达1.656×10^(-6)S·cm^(-1)。
The glass-forming region in the ZrF_4-BaF_2-PbF_2 glass system has been determined and the conductivity, the IR-spectrum, DTA, the transport number of fluorine ions and the resistance spectrum have been measured. The glasses are exclusively fluorideion conductors. The conductivities increase with decreasing of ZrF-4 content, the conductivities of compounds 65 ZrF-4-10BaF_2-25PbF_2 have reached 1.656×10^(-6)(S.cm^(-1)) at 200℃. It is known that they are a good glass state fluoride ionic condutor.
