Applications
Mainly used in the manufacture of precision optical glass and optical fibers. Also used in the electronics industry as a dopant for ceramic capacitors and piezoelectric ceramics. Also used as a raw material for the production of lanthanum boride and as a catalyst in petroleum separation and refining.
Applications: Primarily used in the manufacture of special alloy precision optical glass and high-refractive optical fiber boards, suitable for use in cameras, microscope lenses, and prisms for advanced optical instruments. Also used in the manufacture of ceramic capacitors, dopant for piezoelectric ceramics, and X-ray luminescent materials such as lanthanum oxybromide powder. It is obtained by extracting lanthanum cerium phosphate ore or by calcining lanthanum carbonate or lanthanum nitrate. It can also be obtained by thermally decomposing lanthanum oxalate. It is used as a catalyst in various reactions, such as the oxidation of carbon monoxide when doped with cadmium oxide and the hydrogenation of carbon monoxide to methane when doped with palladium. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used in the manufacture of ferrite magnets. It is a highly effective and selective catalyst for the oxidative coupling of methane to ethane and ethylene. Used to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, and to manufacture fiber optic devices and optical glass
