Application
Cerium(III) fluoride (CeF3) is a versatile material with several critical applications, reflecting its unique properties. Primarily recognized for its role in high-energy physics experiments as a scintillator and tunable laser material, CeF3 boasts a luminescent quality due to its 100% activator (Ce3+) concentration. It is an essential component in the glass industry, revered as the most efficient agent for precision optical polishing and used to decolorize glass by maintaining the iron in its ferrous state. In metallurgy, cerium(III) fluoride plays a pivotal role in steel manufacturing, where it removes free oxygen and sulfur by forming stable oxysulfides and eliminates unwanted trace elements like lead and antimony. Additionally, it enhances the brilliance of arc carbons and is involved in the preparation of cerium metal. Cerium(III) fluoride also contributes as a core additive in welding, providing stability to the arc and modifying the flow of molten metal, and is utilized in the production of Lewis acids. It can be synthesized using a variety of methods, including reactions at elevated temperatures, hydrothermal synthesis, and other advanced techniques, resulting in an off-white powder that is insoluble in water and acids.
