· KHF2

KHF2 (potassium bifluoride) is an inorganic ceramic compound composed of potassium and fluoride ions, belonging to the halide ceramic family. It is primarily used in metallurgical processing, glass etching, and uranium enrichment applications, where its strong fluoride ion availability makes it valuable for chemical processing and surface treatment operations. Engineers select KHF2 when high chemical reactivity with metals and oxides is required, though its hygroscopic nature and corrosive characteristics demand careful handling and specialized equipment design.
