Description
Lanthanum Oxide La2O3 Powder Properties
What is Lanthanum Oxide La2O3 ?
Lanthanum oxide is an inorganic compound with the formula La2O3, a white solid. It absorbs water and carbon dioxide easily in the air but is insoluble in water. It has the characteristics of high refractive index, high density, hardness, high thermal conductivity, and high corrosion resistance.
Regarding physical properties, lanthanum oxide has a crystal structure and can take different forms. It can be processed into powder or crystal, has a high refractive index, and is a good optical material.
Regarding chemical properties, lanthanum oxide has high chemical stability, low reactivity to air and water, and will not react with most chemical reagents such as acids, bases, and salts. It has high corrosion resistance and can remain stable without decomposition or oxidation at high temperatures. In addition to the above properties and applications, lanthanum oxide can also form intermetallic compounds with other elements, such as lanthanum aluminum oxide, lanthanum zirconium oxide, etc. These intermetallic compounds have more unique physicochemical properties and broader application prospects, such as preparing high-temperature superconducting, magnetic, and energy storage materials. Therefore, Lanthanum oxide and its intermetallic compound have wide applications and potential for development in the next phase of technology and science.

How is Lanthanum Oxide La2O3 Produced?

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.


Lanthanum Oxide Uses:

Analytical reagent: Lanthanum oxide can be used as an analytical reagent for the detection of rare earth elements and other metal elements, and It is also widely utilized for analyzing trace elements in geology, environmental protection, chemical industry, and other fields.

Catalyst: Lanthanum oxide can be used as a catalyst in petrochemical, automotive exhaust purification, and other fields, which can improve catalytic efficiency and selectivity.

Optical materials: Lanthanum oxide has the characteristics of high light transmission, high refractive index, and low scattering and can be used to prepare optical materials, such as lenses, prisms, and so on.

High-temperature superconducting materials: Lanthanum oxide can form high-temperature superconducting materials with other metal elements, such as La-Ba-Cu-O series high-temperature superconductors. These superconducting materials have high critical temperatures and good superconductivity, which can provide important technical support for energy transmission and storage.

Electronic materials: Lanthanum oxide has good electrical conductivity and thermal stability and can be used to prepare electronic materials, such as resistors, capacitors, etc.

Rare earth permanent magnet materials: Lanthanum oxide can form rare earth permanent magnet materials with other rare earth metal elements, such as SmCo5, Sm2Co17, etc. Permanent magnet materials offer advantages like high coercivity, high resolution, and a high energy magnetic product, which offer crucial technical assistance in generators, motors, and sensors.


Storage Condition of  Lanthanum Oxide La2O3 Powder :

Generally, commercial products are added with polymerization inhibitors. Store in a cool, ventilated warehouse. Keep away from fire and heat. The storage temperature should not exceed 30℃. The packaging needs to be sealed and not in contact with air. It should be stored separately from oxidants, acids, alkalis, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
