應用
用于研究两性聚合物凝胶的离子特异性溶胀和去溶胀的多功能氟离子源。贵金属在氟化氢中的室温氧化, 以及碱金属卤化物聚合物中离子的电子极化率的测量。
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:
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]
