Description and Uses

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.

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.
