99.99% Lanthanum oxide for optical glass manufacturing

  It is mainly used for manufacturing special alloy precision optical glass, high refractive optical fiberboard, suitable for camera, camera, microscope lens and prism of advanced optical instruments. It can also be used to manufacture ceramic capacitors, piezoelectric ceramic admixtures and X-ray luminescent materials such as lanthanum bromide powder. It is obtained by extraction from phosphate cerium lanthanum ore or by burning lanthanum carbonate or lanthanum nitrate. It can also be obtained by heating and decomposing lanthanum oxalate. It can be used as a catalyst for many 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.
