Potassium tetrafluoroborate, identified by CAS number 14075-53-7, is an inorganic chemical compound appearing as a white, crystalline powder or granular solid. It is characterized by its relative stability and low solubility in water compared to other fluoroborate salts. Chemically, it serves as a reliable source of boron and fluorine in various high-temperature industrial processes.
In industrial and research settings, this material is valued for its role as a fluxing agent and grain refiner. It is non-hygroscopic, which facilitates easier handling and storage compared to more moisture-sensitive alternatives. While stable at ambient temperatures, it requires careful management to avoid exposure to strong acids or extreme heat, which may trigger the release of hazardous vapors.
