Lanthanum oxide is an inorganic compound containing rare earth elements lanthanum and oxygen

Overview of lanthanum oxide La2O3 powder

Lanthanum (III) oxide. Lanthanum oxide is a chemical substance with a chemical formula of La2O3. Slightly soluble in water, and produce the corresponding salt. Exposure to the air easily absorbs carbon dioxide and water, and gradually becomes lanthanum carbonate. Combustion of lanthanum oxide and water will give off a lot of heat. Mainly used to manufacture precision optical glass and optical fiber. Is La2O3 an ionic compound or a covalent compound? Therefore, La2O3 is more ionic and Lu2O3 is more covalent. As the size decreases from La to Lu, the stability of the oxygen-containing salt also decreases.

Lanthanum oxide is an odorless white solid, insoluble in water but soluble in dilute acid. According to the pH value of the compound, different crystal structures can be obtained. La2O3 is hygroscopic. In the atmosphere, over time, it absorbs water and becomes lanthanum hydroxide. Lanthanum oxide has p-type semiconductor characteristics, with a bandgap of approximately 5.8 eV. Its average room temperature resistivity is 10kΩ·cm, which decreases with increasing temperature. Among rare earth oxides, La2O3 has the lowest lattice energy and a dielectric constant of 27.

Properties of lanthanum oxide La2O3 powder

Nano lanthanum oxide is a white powder. The density is 6.51 g/cm3. The melting point is 2217°C. The boiling point is 4200°C. Slightly soluble in water, soluble in acid, and generate the corresponding salt. The air easily absorbs carbon dioxide and water and gradually turns into lanthanum carbonate. The calcination and hydration of lanthanum oxide emit a lot of heat. To

How is lanthanum oxide La2O3 powder produced?

1. The raw material of the extraction method is a rare earth nitrate solution after removing cerium, which contains about 50% La2O3, trace amounts of CeO2, 116%-7% Pr6O, and 30% Nd2O3. Preparation of ΣRXOY 320~330g/L rare earth nitrate solution, using neutral phosphine extractant dimethyl heptyl methyl phosphonate (P350), after 35~38 steps of separation by P350 kerosene system to separate lanthanum and other rare earth After the lanthanum containing the raffinate is separated and neutralized by ammonia water, oxalic acid is precipitated, then filtered and burned to obtain the finished lanthanum oxide. It is extracted from phosphorus-cerium lanthanum ore or by burning lanthanum carbonate or lanthanum nitrate. It can also be made by the thermal decomposition of lanthanum oxalate.

2. Put La(OH)3 into a platinum crucible, dry at 200°C, burn at 500°C, and then decompose at 840°C to obtain lanthanum oxide.
