CAS 1312-81-8 High Purity 99.99% Lanthanum oxide
Uses: Mainly used in the manufacture of precision optical glass, optical fiber. Also used in the electronics industry as ceramic capacitors, piezoelectric ceramic doping agent. It is also used as a raw material for the preparation of lanthanum boride, and as a catalyst for petroleum separation and purification.
Applications: Mainly used for the manufacture of special alloy precision optical glass, high-refractive optical fiber board, suitable for cameras, cameras, microscope lenses and advanced optical instrument prisms, etc. It is also used in the manufacture of ceramic capacitors, piezoelectric ceramic dopants and X-ray luminescent materials such as lanthanum oxybromide powder. It is extracted from lanthanum lanthanum ore or obtained by burning lanthanum carbonate or lanthanum nitrate. It can also be obtained by thermal decomposition of lanthanum oxalate. It is used as a catalyst for various reactions, such as catalyzing the oxidation reaction of carbon monoxide when doped with cadmium oxide, and catalyzing the hydrogenation of carbon monoxide to form methane when doped with palladium. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to make ferrite magnets. It is a very efficient selective catalyst for the oxidative coupling of methane to ethane 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 optics and optical glass.
