Description and Uses

Cerium(III) Fluoride (CeF3), in particular, is successfully used in experiments in high-energy physics. As a potential scintillator and a tunable laser material, CeF3 is a luminescent material with 100% activator (Ce3+) concentration. CeF3 has been previously prepared by several methods, including the reaction of CeO2 with fluorine gas at elevated temperature, using high-intensity ultrasound, rapid microwave method, thermal decomposition of precursors, hydrothermal synthesis, synthesis by precipitation from aqueous solutions, sol-gel method, synthesis of nanoparticles in colloidal nanoreactors, solvothermal method and conventional melting technique[1].

Cerium(III) fluoride is used to make Lewis acid. It is considered to be the most effective glass polishing agent for high precision optical polishing. Cerium fluoride used as a core additive to improve the properties of the eventual weld. The fluoride provides stability to the arc and also modifies the behavior of the molten metal flowing into the weld.
