Thulium Metal (Tm) is a silvery-gray rare-earth metal with exceptional softness and ductility, valued for its unique optical and magnetic properties. With a CAS number of 7440-30-4 and an atomic weight of 168.93 g/mol, this metal offers purity levels of 99.9%-99.99% (depending on grade). Characterized by a melting point of 1545°C and a density of 9.32 g/cm³, Thulium Metal is renowned for its role in generating mid-infrared laser light and enhancing magnetic properties in specialty alloys.
1. Mid-IR Laser Emission: When doped into crystals or glasses, Tm³+ ions emit at 1.8-2.0 μm, ideal for medical lasers (e.g., soft tissue ablation) and environmental gas sensing.
2. High Purity & Low Impurities: Stringent purification processes minimize iron, oxygen, and nitrogen contaminants, critical for maintaining optical clarity in laser media.
3. Alloying Versatility: Forms stable alloys with aluminum, nickel, and zirconium, improving corrosion resistance and magnetic permeability in aerospace components.
4. Thermoelectric Properties: Moderate electrical conductivity combined with low thermal conductivity makes it a candidate for thermoelectric generator materials.
5. Oxidation Resistance: Protected by a thin oxide layer in dry air, ensuring long-term stability in non-humid environments.
• Medical Lasers: Tm-doped fiber lasers produce gentle heat for minimally invasive surgeries, such as prostatectomy and dental procedures, due to water absorption at 1.94 μm.
• Environmental Sensing: Used in tunable diode lasers to detect trace gases like methane and water vapor in industrial emissions monitoring.
• High-Tech Alloys: Added to magnesium alloys to refine grain structure, enhancing strength and creep resistance for aircraft engine components.
• Magnetic Materials: Combined with cobalt to create permanent magnets with high coercivity for compact electric motors in robotics and drones.
• Research & Development: Serves as a reference material in X-ray fluorescence (XRF) analysis and as a dopant in single-crystal growth for academic studies.
Q: What forms does Thulium Metal come in?
A: Available as ingots, rods, granules, and sputtering targets to suit different manufacturing processes.
Q: How is Thulium Metal protected during shipping?
A: Packed in argon-filled sealed containers or vacuum-sealed bags to prevent oxidation during transit.
Q: Can it be used in cryogenic applications?
A: Yes, it maintains ductility at low temperatures, making it suitable for cryogenic sensors and superconducting magnet components.
Q: What is the primary difference between Thulium Metal and Thulium Oxide?
A: The metal is used for alloying and metallic coatings, while the oxide is preferred for ceramic matrices and optical doping.
Q: Are there any restrictions on exporting Thulium Metal?
A: Export compliance varies by region; our team will assist with necessary permits and documentation based on your destination.
