· JVASP-58331· Na2LiAlF6

Na2LiAlF6 is a mixed-metal fluoride compound belonging to the class of fluoride salts, combining sodium, lithium, and aluminum fluoride constituents. This material is primarily investigated for use in molten salt systems, particularly in advanced nuclear reactor coolants (such as molten salt reactor designs) and as an electrolyte component in high-temperature electrochemical processes, where its thermal stability and ionic conductivity are advantageous. Compared to single-component fluoride salts, this ternary composition offers tuned melting behavior and chemical compatibility characteristics relevant to next-generation energy technologies.
