Lanthanum Oxide La2O3 CAS 1312-81-8

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.
