Used as a catalyst in organic synthesis, particularly in fluorination reactions where selective introduction of fluorine atoms is required. Plays a role in the production of specialty fluorides and ceramics due to its thermal stability and reactivity. Employed in metallurgy for flux formulations in aluminum and magnesium alloy processing. Also investigated for use in lithium-ion battery materials as a precursor for iron-based cathodes. Its ability to form complex fluorometallates makes it useful in chemical research and development of new inorganic compounds.
