Product Description
Lanthanum oxide is a white amorphous powder. The density of 6.51g/cm3. The melting point of 2217 DEG C. Boiling point is 4200 ºC. Slightly soluble in water, soluble in acid and generates the corresponding salts. Exposed to air is easy to absorb carbon dioxide and water, gradually become lanthanum carbonate. Burning lanthanum oxide hydrate release a lot of heat.

Application
1.The main application areas for the manufacture of special alloy precision optical glass with high refractive index, optical fiber board, suitable for the camera, camera, microscope lens and senior optical prisms.
2. Used in the manufacture of ceramic capacitor, piezoelectric ceramic doping agent and X ray luminescence materials with lanthanum oxide powder. Ceriu m lanthanum phosphorus ore by extraction or by burning or l anthanum nitrate and lanthanum carbonate.
3.Mainly used in the manufacture of precision optical glass, optical fiber. Also used in the electronics industry for ceramic capacitor, piezoelectric ceramics doped with agent. Also used for preparing lanthanum boride raw material, the separation of petroleum refining catalyst.
4.
Used as catalysts for many reactions, such as doped ca dmium oxide catalytic carbon mon oxide oxidation reaction, doped palladium catalytic hydrogenation of carbon mon oxide to generate metha ne reaction. Leach into the lithium oxide or zirconium oxide lanthanum oxide ( 1% ) can be used for manufacturing ferrite magnet.
