An irritant. | [Description]
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]. | [Chemical Properties]

Cerium Fluoride, is the important raw material for polishing powder, special glass, metallurgical applications. In glass industry, it is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolorize glass by keeping iron in its ferrous state. In steel manufacturing, it is used to remove free Oxygen and Sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony.
