Used in the production of fluorinated compounds and as a catalyst in organic synthesis, particularly in fluorination reactions. Employed in the manufacture of specialty glasses and ceramics due to its ability to modify refractive index and improve thermal stability. Also utilized in surface treatment processes for metals and semiconductors, where it helps form protective fluoride layers. Plays a role in the development of certain types of lithium-ion batteries by contributing to solid electrolyte interface stabilization. Investigated for use in dental products for enamel strengthening, similar to other fluoride-releasing compounds.
