Description

Lutetium is a rare earth metal, the hardest and densest of the lanthanide series, known for its exceptional purity and specific nuclear properties. This high-value material is critical for advanced technology sectors requiring precise and reliable performance. It is primarily sought by manufacturers and research institutions in the fields of cancer therapy, petroleum refining catalysts, and high-performance phosphors.

Application

• Medical Radioisotopes: Used as the parent material for Lutetium-177, a vital β-emitting isotope for targeted radionuclide therapy (TRT) in treating neuroendocrine tumors and prostate cancer.
• Petroleum Refining Catalysts: Serves as a key component in fluid catalytic cracking (FCC) catalysts to enhance yield and selectivity in gasoline production.
• Phosphors and Scintillators: Doped into crystals like Lutetium Oxyorthosilicate (LSO) for use in positron emission tomography (PET) scanners and other radiation detection equipment.
• Specialty Alloys: Added in small quantities to improve the strength and workability of other metals.
• Research & Development: Utilized in academic and industrial labs for studies in magnetism, superconductivity, and as a dopant in optical fibers.
• LED Technology: Acts as a dopant in certain phosphors to fine-tune the color output and efficiency of light-emitting diodes.

Quality Control

Our lutetium metal is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and traceability. We offer various purity grades, including 3N (99.9%), 4N (99.99%), and 5N (99.999%), tailored to specific application requirements. A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical form is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, lutetium metal must be stored under an inert atmosphere such as argon or in mineral oil. Store in a cool, dry, well-ventilated area away from incompatible materials. For long-term storage, maintain at room temperature (15-25°C) in a controlled humidity environment.
