Rare Earth Oxide-Lanthanum Oxide

Lanthanum oxide is a chemical substance and its molecular formula is La2O3. Slightly soluble in water, soluble in acid, easy to absorb carbon dioxide and water in the exposed air, mainly used to make precision optical glass and optical fiber.


Mainly used to manufacture precision optical glass and optical fiber. Also used in the electronics industry as ceramic capacitors, piezoelectric ceramic dopants. It is also used as a raw material for lanthanum boride and a catalyst for petroleum separation and refining.

Application areas:

  1. Mainly used in the manufacture of special alloy precision optical glass, high-refraction optical fiber board, suitable for cameras, cameras, microscope lenses and advanced optical instrument prisms.
  2. It is also used in the manufacture of ceramic capacitors, piezoelectric ceramic dopants and X-ray luminescent materials, such as lanthanum bromide powder. It is obtained by extracting lanthanum phosphite or burning lanthanum carbonate or lanthanum nitrate. It can also be obtained by thermal decomposition of lanthanum oxalate.
  3. Used as a catalyst for various reactions, such as catalyzing the oxidation reaction of carbon monoxide when doped with cadmium oxide, and catalyzing the reaction of carbon monoxide hydrogenation to methane when doped with palladium. It is a very effective selective catalyst for the oxidative coupling of methane to ethane and ethylene.
  4. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to make ferrite magnets.
  5. Used to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, and to manufacture fiber optics and optical glass.
