The following is a list of the most recent articles about Lanthanum Oxide, La2O3, :
What is the name for La2O3?
Lanthanum(III) oxide. Lanthanum oxide chemical formula It is a good idea to use a bilingual translator La2O3 . The salts are produced by a slight soluble solution in water. Expose to air easily absorbable carbon dioxide and water. Gradually convert into lanthanum Carbonate. The combination of burning water and lanthanum dioxide produces heat. Mostly used in the production of optical fiber and precision optical glasses.
Is La2O3 covalent or ionic?
La2O3 consists of more ionic ions and Lu2O3 contains more covalent ions. The stability of the oxosalts also decreases with the decrease in size from La-Lu.
Lanthanum Oxide is a solid white odorless substance that is insoluble with water, but soluble with dilute acids. Different crystal structures are possible depending on the value of pH. La2O3 possesses hygroscopic characteristics. It absorbs water in the air and becomes lanthanum hydroxide. Lanthanum dioxide has p type semiconductor properties with a gap of 5.8 eV. Its resistivity at room temperature averages 10 kO*cm and decreases with temperature. La2O3 in rare earth oxides has the lowest dielectric constant and lattice energy.

Performance of Lanthanum Oxide, La2O3 powder
The white powder consists of nanometer lanthanum dioxide . The density of this powder is 6.51g/cm3. Its melting point is 2216. The boiling point 4200. Slightly soluble, it is soluble in acid and can be converted to salts. The carbon dioxide in the air and water is readily absorbed by the air, resulting in lanthanum. The heat is produced by the hydration of lanthanum and calcination.

How do you pronounce Lanthanum Oxide, La2O3, Produced?
1. The extraction method uses rare earth nitrate after cerium removal, which contains around 50% La2O3, trace amounts of CeO2, 116%-70% of Pr6Oand 30 % of Nd2O3. The preparation of S RYOY 320330g/L rare earth nitrate using a neutral phosphine agent methyl-phosphonic acid dimethyl-heptyl ester (P350), after 3538 stage extraction separation, separation of Lanthanum and rare earth It can be extracted by burning lanthanum carbohydrate or lanthanum nitrogen. You can also make it by heating lanthanum Oxalates.
2. La(OH)3 can be placed into a platinum-based crucible and dried at 200°C. Then, it is burned at 500°C, before being decomposed at 840°C to yield lanthanum.

Lanthanum Oxide: :
Inorganic Lanthanum oxide contains rare earth elements, lanthanum as well as oxygen. It’s used in ferroelectric materials as well as optical materials and as a catalyst feedstock.
Lanthanum Oxide Other Applications: Mainly used in the manufacturing of precision alloy optical glass, high-refraction optical fibreboard, suitable to the camera, microscope lens, and prisms of advanced optical devices.
Lanthanum is used to produce ceramic capacitors as well as piezoelectric ceramics and X ray luminescent materials like lanthanum chloride oxide powder.
Lanthanum is also used as catalysts for various reactions. These include the oxidation and hydrogenation of carbon dioxide when it’s doped with cadmium.
Ferrites can be produced using Lanthanum Oxide infiltrated by lithium oxide or zirconia (1%).
Lanthanum Oxide is an effective and select catalyst for the oxidative conversion of methane into Ethane and Ethylene.
Lanthanum dioxide is used for improving the temperature dependence of ferroelectric materials barium titanate(BaTiO3) (and strontium titanate(SrTiO3)), as well as manufacturing fiber optical devices, optical glasses and other optical glasses.

Storage condition of Lanthanum Oxide (La2O3 powder) :

Commercial products usually contain polymerization inhibitors. Store in an air-conditioned, cool storage facility. Keep away from heat and flames. The temperature of the storage area should not be higher than 30°C. Packaging must be sealed to prevent air contact. Avoid mixing storage and store it separate from oxidants. Use explosion-proof lighting, ventilation and other facilities. The use of spark-prone tools and mechanical equipment is prohibited. The storage area needs to be equipped both with appropriate containment material and emergency leakage treatment equipment.

Packing & Shipping Lanthanum Oxide La2O3 Particles :
