About Lanthanum Oxide (La2O3) :
What’s the name of La2O3?
Lanthanum(III) oxide. Formula for Lanthanum Oxide It is La2O3 . It is slightly insoluble in water. Inhale the gas to make lanthanum carbonate. Burning lanthanum dioxide and water together gives off great heat. It is mostly used to make precision optical glasses, or optical fiber.
Do you consider La2O3 to be an ionic, or covalent compound.
La2O3 tends to be more ionic, while Lu2O3 can be more covalent. Stability of oxos salts drops as La becomes smaller.
An odorless, white solid is Lanthanum oxide. It’s insoluble with water and dissolves in dilute acids. Different crystal structures may be possible, depending on what the pH value is. It has excellent hygroscopic qualities. Over time, it becomes lanthanum oxide in the atmosphere. It has semiconductor properties of p-type and an electron bandgap around 5.8eV. Its room temperature resistivity averages 10 kO *cm and decreases with temperature. La2O3 in rare earth oxides has the lowest Lattice Energy and the greatest dielectric constant of 27.

Lanthanum Oxide, La2O3 powder performance:
Nanometer-sized lanthanum dioxide is an example of white powder. It is 6.51g/cm3. The ability to absorb carbon dioxide from air is quite easy. Later, the chemical became lanthanum carbate. Hydration, as well as calcination of lanthanumoxide will result in a significant amount of heat being released.

It is simple. Lanthanum Oxide (La2O3) Produced?
1. Rare earth nitrate solution is the main raw material. This solution has been removed of cerium and contains around 50% of La2O3. It also contains trace amounts of CeO2, 16% to 7% of Pr6O and 30% of Nd2O3. The preparation of SXOY320 330g/L rare earth. You can extract it from phosphor – cerium lanthanum, lanthanum carbonate and lanthanum nuitrate. Also, it can be obtained by heating the lanthanum-oxalates.
2. La(OH)3 can be placed in a platinum pan, dried at 200 and then burned at 500. Then, decompose the aluminum over 840 to get lanthanumoxide.

Lanthanum Oxide Applications :
The inorganic compound Lanthanum Oxide is made up of the rare elements lanthanum as well as oxygen. It can be used to make ferroelectric material, or as a part of optical materials.
Other applications of Lanthanum oxide: It’s used mainly in the production of precision alloy optical glasses, high refraction optic fiberboard and camera lenses.
The manufacture of ceramic capacitors, piezoelectric ceramic additions, and X-ray luminescent material such as lanthanum brmide oxide powder is done with lanthanum dioxide.
As a catalyst, Lanthanum oxide can be used in a number of reactions such as the oxidation carbon monoxide when doped by cadmium oxide or the hydrogenation carbon monoxide into methane.
For the production of ferrite magnets, lanthanum dioxide can be infiltrated (1%) with lithium oxide (or zirconia)
For the oxidative co-upling of methane to other ethanes and ethylene, Lanthanum Oxide is an effective and select catalyst.
To improve temperature dependence and dielectric property of ferroelectric materials barium titanate and strontium titanate, (BaTiO3) ferroelectrics, and also to fabricate fiber optical devices and glasses. Lanthanum dioxide is also used.

Storage condition of Lanthanum Oxide (La2O3) Powder –

Commercial products generally contain polymerization inhibitors. You should store them in a well-ventilated warehouse. Do not expose to heat or fire. Storage temperature shouldn’t exceed 30°F. It is important that the packaging be properly sealed. The packaging should be kept away from acids and oxidants as well as other substances. You should use ventilation and explosion-proof lighting. Avoid using any mechanical devices or tools that can easily produce sparks. It is important to have appropriate containment material and emergency equipment for leaking in the storage area.
