Abstract

The structure, thermal and some physical properties of lead fluoroborate glasses containing 30 mol% SiO2 have been investigated by differential thermal analysis, X-ray diffraction and Fourier-transform infrared spectroscopy. The glasses were prepared by the conventional melt-quenching method. Fourier-transform infrared spectroscopy results showed that the network of these glasses consists mainly of BO3, BO4, SiO4, and PbO4 structural units. The thermal stability of the glass samples determined by differential thermal analysis was found to be about 80°C. Dilatometric measurements showed that the glass transition temperature and dilatometric softening temperature decrease with increasing lead content, whereas the coefficient of thermal expansion increases. The density and molar volume increased with the increase in lead content. The conductivity of the investigated glasses mainly depends on the mobility of F– and Pb2+ ions. The variation in volume resistance upon changing the composition has been correlated with the structural changes in the glass network. The results obtained in this study indicate that the investigated glasses can be potential candidates for advanced technologies as solder and sealing materials.

pbo - pb_2 - b2o3 - sio2玻璃的合成、结构与性能

用差热分析、X射线衍射和傅立叶变换红外光谱研究了含30 mol%SiO2的氟硼酸铅玻璃的结构、热性能和一些物理性能。采用传统的熔融淬火方法制备了玻璃。傅立叶变换红外光谱结果表明，这些玻璃的网络主要由BO3、BO4、SiO4和PbO4结构单元组成。通过差热分析确定的玻璃样品的热稳定性约为80°C。膨胀测量表明，随着铅含量的增加，玻璃化转变温度和膨胀软化温度降低，而热膨胀系数增加。密度和摩尔体积随着铅含量的增加而增加。所研究的玻璃的导电性主要取决于F-和Pb2+离子的迁移率。改变组成时体积电阻的变化与玻璃网络的结构变化有关。本研究的结果表明，所研究的玻璃可以作为先进技术的焊料和密封材料。
