1 used in the manufacture of special alloy precision optical glass, high refractive index optical fiber board, suitable for camera, camera, microscope lens and advanced optical instrument prism, etc. .,
2 used in the manufacture of ceramic capacitors, piezoelectric ceramic doped agent and X - ray luminescent materials, such as lanthanum bromide.
3 used as a catalyst for a variety of reactions, such as the oxidation of carbon monoxide when doped with cadmium oxide reaction, the reaction of carbon monoxide hydrogenation to produce methane.
4 impregnated lithium oxide or zirconium oxide (1%) lanthanum oxide can be used in the manufacture of ferrite magnets.
5 is a very effective selective catalyst for the oxidative coupling of methane to ethylene and ethylene.
6 for improving the temperature dependence and dielectric properties of barium titanate (BaTiO3), strontium titanate (SrTiO3) ferroelectric, and the fabrication of fiber optic devices and optical glass.
Carbonate precipitation method to the extraction separation of lanthanum chloride solution as raw materials, ammonium bicarbonate and precipitation of lanthanum carbonate, by heating, aging, washing, separation, and burning of lanthanum oxide. Can be prepared by heating the decomposition of lanthanum oxalate.
