 Slightly soluble in water, soluble in acid to generate the corresponding salts. Easy to absorb carbon dioxide and water when exposed in air, has gradually become the lanthanum carbonate. Burning of lanthanum oxide and 

 Hydrate to release a lot of heat. The main application areas for special alloys precision optical glass manufacturing system, high-refraction optical fiber board, suitable for the camera 

 Microscope lens, camera, and advanced optical instruments prism. Also used in the manufacture of ceramic capacitors, piezoelectric ceramic incorporation agents and X-ray luminous materials bromine oxygen 

 Of lanthanum powder. Phosphorus cerium and lanthanum ore extraction or derived by the burning of lanthanum lanthanum carbonate or nitrate. By lanthanum oxalate thermal decomposition can be obtained. Used as a multi- 

 Kinds of catalysts, such as doping the catalytic oxidation of carbon monoxide in cadmium oxide doped with palladium reaction when catalytic hydrogenation of carbon monoxide, methane generation. Soak 

 Infiltration of lithium oxide or zirconium oxide (1%), lanthanum oxide can be used in the manufacture of ferrite magnets. Very effective option for the oxidative coupling of methane to ethane and ethylene 

 Sexual catalyst. Used to improve the barium titanate (BaTiO3) and strontium titanate (of SrTiO3) the temperature dependence of the ferroelectric and dielectric properties, and manufacture of fiber optic device 

 Pieces of optical glass.
