What Is Potassium Fluoride?
Potassium fluoride is an inorganic compound, appearing as a white crystalline or powdered substance. This compound is notable for its solubility in water, insolubility in ethanol and other alcohols, and its ability to corrode glass, imparting a salty taste.
Key data for potassium fluoride include its chemical formula KF, molecular weight of 58.10, melting point of 860°C, and boiling point of 1505°C. Its CAS registration number is 7789-23-3. Potassium fluoride is regulated under several safety and environmental laws, necessitating proper handling and labeling.
Uses of Potassium Fluoride
Potassium fluoride’s applications are diverse, spanning multiple industries:
- It serves as a crucial raw material in the manufacturing of tantalum for tantalum capacitors, vital components in electronics.
- As a base in organic reactions, potassium fluoride acts as a fluorinating agent, catalyst, and fluxing agent, also absorbing HF and moisture in organic synthesis.
- Additionally, it is utilized as an analytical reagent, complex-forming agent, and in food preservation, electroplating, and etching processes.
- Potassium fluoride is also employed in the preparation of aluminum welding rods and welding flux, alongside being a precursor for potassium hydrofluoride.
Given its hazardous classification under safety laws and others concerning transport, aeronautics, water pollution, air pollution, and soil contamination, potassium fluoride requires diligent handling and proper disposal measures.
