Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid, that transitions to white with decreasing crystal size.Although odorless, lithium fluoride has a bitter-saline taste. Its structure is analogous to that of sodium chloride, but it is much less soluble in water.It is mainly used as a component of molten salts. Formation of LiF releases one of the highest energy per mass of reactants, only second to that of BeO.ithium fluoride is exceptionally chemically stable and LiF/BeF 2 mixtures (FLiBe) have low melting points (360 C - 459 C) and the best neutronic properties of fluoride salt combinations appropriate for reactor use.
