The Potassium Tetrafluoroborate (KBF₄) is a white, crystalline powder soluble in water, with the chemical formula KBF₄. It exhibits stability at room temperature and serves as a fluoride source in many chemical reactions.

KBF₄ is typically produced by reacting boric acid or boron compounds with hydrofluoric acid and potassium salts under controlled conditions. Purity and particle size are carefully controlled to meet industrial standards, as these factors affect its efficiency in electroplating and flux applications.

Modern production emphasizes environmental safety, controlled handling of fluorides, electroplating chemical, flux additive, potassium fluoroborate compound, metal surface treatment chemical, industrial plating reagent and minimal impurities, ensuring consistent performance in downstream processes.
