摘要: 熔融硝酸盐在新能源存储和利用以及工业生产中占有很重要的位置,了解熔盐的结构及其在混合过程中的结构变化,有助于熔融硝酸盐的高效使用。实验按照不同的配比得到二元混合硝酸盐样品,并采用高温显微激光拉曼(Raman)光谱仪测定了不同温度下混合硝酸盐的Raman光谱图。通过对固态和熔融态混合硝酸盐的结构信息的分析,得到了混合盐在升温过程中结构的变化,并使用分光光度法得到熔盐在高温下的分解状况。

关键词: 混合硝酸盐, Raman光谱, 分解

Abstract: Molten nitrate plays an important role in new energy storage and utilization and industrial production.To understand the structure of the molten salt as well as its structure′s change in the mixing process,it has a great help for its high-effective future application.A lot of binary nitrates were made according to different mix ratios,and thermo-Raman spectrophotometer was used to determine the Raman spectra of the mixed nitrates at different temperatures.The structure changes of mixed nitrates in the process of heating up were obtained by comparing the information of the solid and the molten mixed nitrates.The decomposition situation of molten salt at high temperature was also obtained by spectrophotometric method.

Key words: mixed nitrate, Raman spectroscopy, decomposition
