• Description: Lanthanum trifluorides (chemical formula: LaF3) is a kind of high-melting, ionic compound of lanthanum and fluorine. It is a component of the multimetal fluoride glass such as ZBLAN. It is majorly used as a solid membrane electrode for manufacturing the into fluoride sensitive (F-1) Ion-selective probes. It also has applications in fiber optics, fluorescent lamps and radiation applications. Lanthanum fluoride can also be doped with Nd3+ and has special applications as a scintillating material.
• Uses: Lanthanum fluoride is used in phosphor lamp coating. Mixed with other rare earths, it is used in carbon arc electrodes and lasers. Also, the fluoride is used in the production of lanthanum metal, an intermediate step in the manufacture of high purity metal. Lanthanum fluoride, is mainly applied in specialty glass, water treatment and catalyst, and also as the main raw materials for making Lanthanum Metal. Lanthanum Fluoride (LaF3) is an essential component of a heavy Fluoride glass named ZBLAN. This glass has superior transmittance in the infrared range and is therefore used for fiber-optical communication systems. Mixed with Europium Fluoride, it is also applied in the crystal membrane of Fluoride ion-selective electrodes. Lanthanum fluoride, anhydrous is employed extensively in the preparation and study of fluoride glasses. Lanthanum fluoride is a white powder used to coat the inside of phosphorus lamps and lasers.
• Physical properties: White hexagonal crystal; hygroscopic; density 5.9 g/cm3; melts at 1,493°C; insoluble in water and acids.
