摘要
介绍了合成高纯无水的LiBF_4和LIAsF_6的新方法,并讨论了其合成条件,指出制备多孔状LiF和控制反应温度是合成的关键。拉曼光谱分析表明,LiBF_4产品同进口标准样品基本一致,在同样条件下制备的LiASF_6的拉曼谱同文献值一样。
The methods and optimum conditions for thepreparation of LiBF4 and LiAsF6 of high purity werestudied, and it was found that the preparation ofporous, highly reactive LiF and the reaction temperature were the main keys to high yields of the products.From the comparison of the Raman spectrum of theLiBF4 synthesized with that of exotic reference material it was found that the LiBF4 had the same quality.The Raman spectrum of the LiAsF6 produced underthe same conditions is in agreement with that in theliterature.
