Potassium tetrafluoroborate (Csat No.: M051406) is an inorganic salt composed of potassium ions and the tetrafluoroborate anion. It appears as a white crystalline solid and is soluble in water. Commonly used as a fluorinating agent, it also serves as a source of the BF₄⁻ ion in chemical synthesis and catalysis. KBF₄ finds applications in electroplating, metal refining, and as a flux in metallurgy. Its thermal stability and ionic nature make it useful in ionic liquids, ceramics, and advanced material formulations.
