Beschreibung
Lutetium oxide (Lu2O3), also known as lutecia, has a cubic crystal structure and available in white powder form. This rare earth metal oxide exhibits favorable physical properties, such as a high melting point (around 2400°C), phase stability, mechanical strength, hardness, thermal conductivity, and low thermal expansion. The compound is also known to have a wide bandgap of 5.2–5.5 eV and a high-κ dielectric constant of about κ=11–13. The high density of Lu2O3 is utilized in scintillators and in various activators due to its wide bandgap. Due to its excellent physical properties lutetium oxide is considered to be an excellent phosphor host material.
Chemische Eigenschaften
white powder(s); cub crystal(s); absorbs H2O and CO2; as an evaporated material of 99.9% purity is reactive to radio frequencies [HAW93] [CER91] [STR93] [MER06]
Verwenden
Lutetium(III) oxide serves as a catalyst in a variety of reactions such as polymerization, hydrogenation and alkylation reactions. It is also used in ceramics and glass. In the production of laser crystals, lutetium(III) oxide finds application as an important starting material. Its luminescent properties, a field of interest for researchers and may find potential application in biological fields.
Verwenden
Lutetium oxide (Lu2O3), the oxide found in monazite ore, is a white solid. It is hygroscopic and also absorbs carbon dioxide, making it useful to remove CO2 in closed atmospheres.
Verwenden
Lutetium Oxide, also called Lutecia, is the important raw materials for laser crystals, and also have specialized uses in ceramics, glass, phosphors, lasers. Lutetium Oxide also be used as catalysts in cracking, alkylation, hydrogenation, and polymerization. Stable Lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications.
