Physical Properties:

Magnesium fluoride is similar to calcium fluoride and transmits deep into the vacuum ultraviolet. Magnesium fluoride is more resistant to solarization than calcium fluoride, making it more useful for 193-nm excimer laser beam delivery or other laser optics.

Application:

Potassium Fluoride (KF) is a versatile compound used in various industries and applications, ranging from chemical synthesis to electronics and more.

• Industrial Textile Processing and Laundries: Potassium fluoride solution is employed for pH adjustment in industrial textile processing facilities and laundries. It helps in maintaining the desired pH levels in these processes.
• Chemical Synthesis: KF serves as an intermediate or raw material in chemical synthesis and processes. It is frequently utilized in the production of agrichemical and pesticide products.
• Nucleophilic Fluorination Reactions: KF is a key reagent for nucleophilic fluorination reactions. In recent years, various promoters and catalysts, such as ionic liquids, modified crown ethers, and transition metal catalysts, have been used to enhance the reactivity, selectivity, and efficiency of KF in nucleophilic substitution reactions.
• Versatile Organofluorine Compounds: KF, in combination with catalysts or promoters, is employed to synthesize versatile organofluorine compounds, expanding its utility in organic chemistry.
• Applications in Various Industries: KF is used in glass engraving, food preservation, and plating. It can also act as a welding flux, insecticide, catalyst, and absorbent (for HF and moisture). It is utilized as a fluorinating agent for organic compounds, particularly in the production of agrichemical and pesticide products.
• In the Electronics Industry: In the field of electronics, potassium fluoride is used for post-deposition treatment (KF-PDT) in the production of CIGS solar cells, leading to improved cell conversion efficiency.
