NaNO2-KNO3-NaNO3三元熔盐体系的物理化学性质与结构进行了深入 研究。 材料和方法: 实验材料包括分析纯的NaNO2、KNO3和NaNO3,实验设备包括热分析 仪(如DSC/TGA)、光谱仪(如FTIR、Raman)、电导率计和X射线 衍射仪。实验方法包括热分析、光谱分析、电导率测量和X射线衍射。
本实验研制了高温原位紫外-可见吸收光谱仪,并结合标准的电子顺磁共振谱仪来研究HTS(53wt%KNO3—40wt%NaNO2-7wt%NaNO3)熔盐分解过程中是否产生超氧离子.实验结果表明NaNO2相对于NaNO3更易于产生超氧负离子,并且熔盐中的超氧负离子在420~440nm有吸收峰,在HTS熔盐中该吸收峰随温度升高发生红移.这个吸收峰可归属为NaO2...
(HTS,53 wt% KNO3/40 wt% NaNO2/7 wt% NaNO3).It is found that the superoxide is m ore easily generated from molten NaNO2 com pared to NaNO3,and it has an absorption band at 420—440 nm in HTS which red shifts as temperature increases.The band is assigned to charge—transfer transition...
