Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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.
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.
ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
For general uses, product is also available in powdered form (449148)
