Nanopowder Compounds

Lanthanum fluoride is used as the "high-index" component in multilayer optical elements such as ultraviolet dichroic and narrowband mirrors. Fluorides are among the most commonly used compounds for UV optical coatings due to their relative inertness and transparency in the far ultraviolet.

Lanthanum fluoride nanoparticles can be dispersed in any kind of lubricating medium. Some of the other names by which these particles are known, as are lanthanum fluoride and trifluorolanthanum. Lanthanum belongs to Block F, Period 6 while fluorine belongs to Block P, Period 2 of the periodic table. Lanthanum fluoride nanoparticles exhibit good physical and chemical stability.

Lanthanum fluoride nanoparticles appear in the form of white spherical metal particles having a high specific area. Lanthanum fluoride is used  As additives to anti-frictional lubricants. Lanthanum fluoride is also used in fluoride selective electrodes.

Lanthanum fluoride is used in oil refining, etching, pharmaceuticals and synthetic organic chemistry. Bonding is ionic with lanthanum highly coordinated. The cation sits at the center of a trigonal prism. There are also two fluorides a little further away above and below the prism. Lanthanum fluoride is used in oxygen-sensitive applications such as metal production.

Lanthanum fluoride is a refractory ionic compound of lanthanum and fluorine. Fast fluoride ion conducting materials exhibit high value of ionic conductivity with negligible electronic conductivity at ambient temperature in comparison to oxygen ion conducting materials and thus find many potential electrochemical device applications.
