Lanthanum Oxide

Description

White solid powder, slightly soluble in water, easily soluble in acid, easy to absorb carbon dioxide and water in dew air.

Application Area

Mainly used for manufacturing special alloy precision optical glass, high refraction optical fiber board, suitable for camera, camera, microscope lens and advanced optical instrument prism, etc. It is also used to manufacture ceramic capacitors, piezoelectric ceramic admixtures and lanthanum bromide powder as X-ray luminescent materials. It is obtained by extraction from the ore or by burning lanthanum carbonate or lanthanum nitrate. It can also be made by heating up the oxalates of lanthanum. It can be used as a catalyst for many reactions, such as the oxidation of carbon monoxide by doping cadmium and the hydrogenation of carbon monoxide to methane by doping 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 oxidation coupling of methane to ethane and ethylene. To improve the temperature dependence and dielectric properties of barium titanate (BaTiO3), Strontium titanate (SrTiO3) ferroelectric bodies, and to manufacture fiber optical devices and optical glass.
