Abstract : The report describes a technique for preparing and purifying the fluoride salt eutectic of LiF, NaF, and KF (Flinak) which has been proposed for use as the electrolyte in a thermal battery system. The method involves the use of bromine pentafluoride, BrF5, to react with and to remove water and oxide impurities in the Flinak. Quantitative analysis of Flinak samples purified in this manner was performed, and the results are compared to those obtained by other currently employed purification techniques. (Author)
