Lanthanum Oxide Uses:Lanthanum hydroxide method: Lanthanum hydroxide is added to hydrogen peroxide for reaction to obtain lanthanum oxide. The benefits of this method are a low level of reaction and simple operation, but it requires a large amount of lanthanum hydroxide raw material and high production cost.
Lanthanum oxychloride method: Lanthanum oxychloride is heated and decomposed to produce lanthanum oxide. The advantages of this technique are that it has a low number of reaction conditions, as well as simple operation. Still, it must use a large amount of lanthanum oxychloride raw material and high production costs.
High-temperature decomposition method: lanthanum carbonate or lanthanum hydroxide is added to carbon and heated to high temperatures to produce elemental lanthanum and carbon dioxide. Elemental lanthanum is then reacted with chlorine gas to produce lanthanum chloride. Lanthanum chloride is then reacted with hydrogen peroxide to produce lanthanum chloride, and finally, lanthanum oxide is heated to decompose lanthanum chloride. The advantages of this technique are a low level of reaction and simple operation, but it needs to use a lot of carbon and chlorine raw materials, and the production cost is high.
Ion exchange method: using rare earth metal salts as raw materials, dissolving them in solvents, and then adding ion exchangers to react to produce rare earth ion exchange resin and ammonium chloride. Lanthanum oxide can be produced by heating the produced rare earth ion exchange resin to high temperatures and burning it. The advantages of this method are low production cost and easy industrial production, but the need to use a lot of rare earth metal salt raw materials.

Application
|
It is mainly used to manufacture special alloy precision optical glass, high refractive optical fiber board, suitable for making
cameras, microscope lenses and advanced optical instrument prisms, etc. It is also used to manufacture ceramic capacitors, piezoelectric ceramic dopants and X-ray luminescent materials such as lanthanum bromide oxide powder. It is used as a catalyst for various reactions. Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to manufacture ferrite magnets, fiber optical devices and optical glass. |
