说明

應用

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. 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.

KF can also be used as:

• A fluxing agent in the field of metallurgy for metal-joining operations, including welding, soldering, and brazing.
• An etching agent in the manufacture of some optical glasses.
• An additive in the formation of single crystals to change the crystal structure, crystal size, and crystal morphology.
