Cerium Fluoride

Cerium fluoride is white powder or 3-6mm melt particle of hexagonal crystal system, which is rare earth metal fluoride and a kind of scintillation crystal. It is also a kind of fluorescent powder. CeF3 could be doped with Tb3+, Pr3+, Ce3+, Yb3+, Tm3+, nitrogen, hydroxide radical and so on. Cerium trifluoride owns optical property, such as high density, fast response, high ionic conductivity and so on. It gets use in chemical sensors and optical devices. Furthermore It is a kind of coating material with medium refractive index and transparent range between 300nm and 10μm. So it is a good optical coating material. It is good low refractive index material, which get use in long wave infrared broadband antireflection. Cerium trifluoride gets wide application in infrared and ultraviolet optics. CeF3 absorb moisture and is hard to dissolve in water, which hydrolyze slowly. Cerium dioxide is the raw material.

Cerium trifluoride uses as high pure chemical reagent and evaporation coating material. It is also raw material for scintillation ceramics. Zinc sulfide(ZnS) could mix with CeF3 to produce thin-film optical coating. Cerium trifluoride is also a kind of solid lubricant. Nano CeF3 could improve the high temperature resistance property and wear resistance property of dielectric oil for transformer.
