Lutetium Metal (Lu) is a silvery-white rare-earth metal renowned for its exceptional density, corrosion resistance, and unique optical properties. With a CAS number of 7439-94-3 and an atomic weight of 174.97 g/mol, this metal offers purity levels of 99.9%-99.995% (4N-5N), featuring a melting point of 1663°C and a density of 9.84 g/cm³—the highest among all lanthanides. Its combination of high thermal conductivity, low neutron absorption cross-section, and ability to form stable intermetallic compounds makes it indispensable in high-precision industrial and optical systems.
1. Ultra-High Purity: Stringent purification via vacuum distillation ensures transition metal impurities (Fe, Ni, Cu) <10 ppm, critical for maintaining optical clarity in laser components.
2. Dimensional Stability: Maintains ductility and formability at elevated temperatures (up to 1000°C), enabling precision machining into complex shapes for aerospace connectors.
3. Optical Reflectivity: High reflectance in the infrared spectrum (8-14 μm) makes it ideal for coating materials in thermal imaging mirrors and astronomical telescopes.
4. Corrosion Resistance: Protected by a tenacious Lu₂O₃ oxide layer in humid air, ensuring long-term reliability in marine and industrial environments.
5. Nuclear Compatibility: Low neutron absorption (5.1 barns) suits it for use in nuclear reactor control systems and radiation shielding materials.
• Optical Coatings: Sputtered as thin films on infrared lenses to enhance reflectivity and reduce thermal emissivity, improving image contrast in night vision devices.
• High-Temperature Alloys: Alloyed with cobalt and chromium to create superalloys for gas turbine blades, increasing creep resistance by 30% at 1200°C.
• Medical Devices: Used in MRI contrast agents as a stable Lu³+ ion source, enabling high-resolution imaging of soft tissues without biological toxicity.
• Research & Development: Serves as a reference material in mass spectrometry and as a dopant in single-crystal semiconductors for quantum computing research.
• Electroplating: Deposited as a protective layer on aluminum components in automotive electronics, leveraging its sacrificial corrosion properties to extend service life.
Q: What forms does Lutetium Metal typically available in?
A: Offered as ingots (1-5 kg), rod stock (diameter 3-20 mm), and sputtering targets (purity ≥99.95%), with custom geometries available via precision casting.
Q: How does its density impact industrial applications?
A: The high density (9.84 g/cm³) provides superior mass efficiency in weight-sensitive aerospace components, while maintaining structural integrity under thermal stress.
Q: Can it be used in cryogenic environments?
A: Yes, it retains mechanical properties down to -200°C, making it suitable for cryogenic valves and superconducting magnet supports.
Q: What is the primary challenge in processing Lutetium Metal?
A: Its high melting point requires specialized furnaces (e.g., electron beam melting) to avoid contamination during casting or welding.
Q: Is there a market for recycled Lutetium Metal?
A: Emerging recycling technologies recover up to 90% from end-of-life optical devices, though current availability remains limited due to low natural abundance.
