Lanthanum Fluoride

Lanthanum fluoride is white face-centered cubic crystal powder, which is rare earth metal fluoride. It is hardly soluble in water, but soluble in alcohol and the dissolution mechanism is same as rare earth chlorides. LaF3 is a kind of optical material, which could be doped with Er3+, Er3+/Yb3+, Nd3+, Ce3+, Tb3+, Pr3+, Eu3+, Yb3+/Tm3+, Ca3+, K3+. LaF3:Nd is a kind of laser material. Their nano particles are luminescent materials. It could improve the mechanical property and wear resistance of Nickel-based self-lubricating alloy as Ni-Cr-Mo-Al-Ti-B-MoS2-LaF3. Lanthanum trifluoride is good low refractive index material, which get use in long wave infrared broadband antireflection. LaF3 could improve the mechanical property of porous titanium, porous aluminum and titanium carbide too. LaF3 is a kind of transparent ceramic material too. It is stable at room temperature and pressure. Lanthanum oxide, lanthanum nitrate or lanthanum chloride is the raw material.

Lanthanum(III) fluoride applies to production of scintillant of modern medical image display and nuclear science requirements, rare earth crystal laser material, fluoride glass optical fiber and rare earth infrared glass. In lighting source, it use in producing carbon electrode of arc lamp. It uses in preparing fluoride ion selective electrode in chemical analysis. In metallurgical industry, it uses in processing special alloy and electrolytic production of lanthanum metal.
