稀土卤化物,尤其是应用广泛的氯化物容易吸湿水解,给熔盐性质的研究带来极大的困难。过去研究含氯化钕的熔盐体系性质时,多采用予先脱水的方法制样,不但工作量大,而且样品在转移过程中很难避免水分和氧气的影响。本工作将氯化铵氯化法直接引入含氯化钕熔盐体系的热分析,操作简便、节省试剂,获得了满意的结 Rare earth halides, especially the widely used chlorides, are easily hygroscopic and hydrolyzed, which brings great difficulties to the study of the properties of molten salts. In the past, when studying the properties of neodymium chloride-containing molten salt system, the method of pre-dehydration was mostly used to prepare samples, which not only resulted in heavy workload but also difficult to avoid the influence of moisture and oxygen during the transfer. In this work, the ammonium chloride chlorination method was directly introduced into the thermal analysis of molten salt system containing neodymium chloride, which is easy to operate, saves the reagent and obtains satisfactory knot
