Applications:

1. It is used to manufacture special alloy precision optical glass and high-refractive optical fiber board, suitable for cameras, cameras, microscope lenses and optical instrument prisms. 

2. It is used in the manufacture of ceramic capacitors, piezoelectric ceramic dopants and X-ray luminescent materials such as lanthanum oxybromide powder.

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 hydrogenation of carbon monoxide to form methane when doped with palladium.

4. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to make ferrite magnets.

5. It is a very effective selective catalyst for the oxidative coupling of methane to ethane and ethylene.

6. It is 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.

Specifications:

Preparation: 

The carbonic acid precipitation method uses the extracted and separated lanthanum chloride solution as the raw material, adds ammonium bicarbonate to precipitate lanthanum carbonate, heats and matures, washes, separates, and then burns into lanthanum oxide. It can also be obtained by thermal decomposition of lanthanum oxalate.
