Lutetium(III) Oxide Powder (Lu₂O₃)
Introduction
Lutetium(III) Oxide Powder (Lu₂O₃) is a rare and highly valuable rare-earth oxide, known for its excellent optical, electronic, and thermal properties. As one of the densest and most stable lanthanide oxides, Lu₂O₃ is extensively used in advanced optics, scintillators, phosphors, and specialty ceramics.
Detailed Description
Lutetium Oxide appears as a white, crystalline powder with a very high melting point (~2,490 °C) and density (~9.42 g/cm³). It is produced in ultra-high purities ranging from 99.9% (3N) to 99.999% (5N), ensuring low impurity levels for demanding applications in electronics and photonics.
Key features include:
High density and stability: Enhances performance in scintillators and ceramic composites.
Optical activity: Used as a host material for rare-earth-doped phosphors and laser crystals.
Thermal stability: Resistant to high temperatures and chemical attack.
Electrical properties: Functions as a high-k dielectric material in microelectronics.
