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. Used to improve the temperature

dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate

(SrTiO3) ferroelectrics, and to fabricate fiber optics and optical glass.
