Mainly used for manufacturing precision optical glass, optical fiber. Also used in the electronic industry as ceramic capacitors, piezoelectric ceramic admixture. It is also used as raw material of lanthanum boride, oil separation and refining catalyst.
Application: Mainly used for making special alloy precision optical glass, high refraction optical fiber board, suitable for camera, camera, microscope lens and advanced optical instrument prism, etc. Also used in the manufacture of ceramic capacitors, piezoelectric ceramic admixture and X-ray luminescence material lanthanum bromide oxide powder. Obtained by extraction of lanthanum phosphocerium ore or by burning lanthanum carbonate. It can also be made by the decomposition of the oxalate of lanthanum by heating. It IS used as a catalyst for various reactions, such as the oxidation of when doped with oxide and the hydrogenation when doped with palladium. Lanthanum oxide impregnated with lithium oxide or zirconia (1%) can be used to make ferrite magnets. It is a very effective selective catalyst for the oxidative coupling and ethylene. It is used to improve the temperature dependence and dielectric properties of Barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, and to manufacture fiber optical devices and optical glasses.
