애플리케이션

A versatile fluoride ion source used in a study of ion-specific swelling and de-swelling of ampholytic polymer gels, in the room temperature oxidation of noble metals in HF, and in the measurement of electronic polarizabilities of ions in polymers of alkali halides.
Potassium fluoride (KF) occurs naturally as the mineral carobbiite. It is mainly used as a fluorinating agent in chemical industries to produce a wide-range of fluorinated compounds by selective fluorination reactions.[1] It also finds application in the electronic industry as a metal surface treatment product. Upon post-deposition treatment of KF in CuInGaSe2 (CIGS) based thin-film solar cells, power conversion efficiency is enhanced. This surface modification has a direct influence on solar cell performance leading to an increase in open-circuit voltage, fill factor, and net charge carrier density of the cell.[2][3]

KF can also be used as:
  • A fluxing agent in the field of metallurgy for metal-joining operations, including welding, soldering, and brazing.[4]
  • An etching agent in the manufacture of some optical glasses.[5]
  • An additive in the formation of single crystals to change the crystal structure, crystal size, and crystal morphology.[6][7]
