설명

일반 설명

Potassium fluoride is a white crystalline solid that is highly soluble in water. It is a strong base widely used in the field of catalysis, polymer synthesis, and semiconductor devices. KF has a relatively high melting point. It dissolves well in hydrofluoric acid. However, KF is insoluble in alcohol.

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 can be used:

• To fabricate CIGS thin films solar cells. Efficiency increased by up to 21.7% after KF postdeposition treatment. This was due to the formation of a K-containing layer on the CIGS surface, which resulted in increased surface reactivity due to the formation of a bilayer structure in which a K—In—Se species covers the CIGSe compound.
• To fabricate 2D vanadium carbide MXene for supercapacitor electrodes.
• To synthesize sulfonyl fluoride through electrochemical oxidative coupling.
• As an electrolyte additive for Li-ion batteries.
• As a catalyst for ring-opening fluorination of cyclic thioethers.
• To synthesize solid base catalysts, KF/Ca−Mg−Al hydrotalcite for the production of Biodiesel via transesterification reactions.
