Overview
Gadolinium targets are high-purity metallic materials primarily used in physical vapor deposition (PVD) processes. As a rare earth element, gadolinium offers unique magnetic and neutron absorption properties that make it valuable for specialized thin film applications. Targets are typically manufactured through vacuum melting and precision machining, available in circular, rectangular, or custom shapes. Industrial-grade targets usually have 99.9%-99.999% (3N-5N) purity, with thicknesses ranging from 1mm to 10mm depending on application requirements.
Physical and Chemical Properties
Gadolinium is a silvery-white, malleable rare earth metal with exceptional thermal neutron capture cross-section (49,000 barns). It exhibits ferromagnetic properties below 20°C (Curie point) and demonstrates the magnetocaloric effect. The metal oxidizes slowly in air, forming Gd₂O₃, and reacts readily with dilute acids. Its high melting point (1312°C) and density (7.90 g/cm³) make it suitable for high-temperature deposition processes. When specifying targets, crystalline orientation (polycrystalline vs. single crystal) significantly affects deposition characteristics.
Main Applications
In semiconductor manufacturing, gadolinium targets deposit thin films for magnetic memory devices and spintronic components. The medical imaging sector utilizes Gd films for neutron radiography and as precursors for MRI contrast agents. Research institutions employ gadolinium targets in neutron detection studies and superconducting material development. Emerging applications include solid-state cooling devices leveraging the magnetocaloric effect, and as doping material in optical coatings for specialized lasers.
Safety and Storage
Bulk gadolinium targets pose minimal hazard, but dust generated during machining requires careful handling. Implement local exhaust ventilation and wear PPE when processing. Store in argon-filled containers or vacuum-sealed bags to prevent oxidation. Disposal must comply with rare earth metal regulations. Unlike some rare earths, gadolinium has low toxicity but powder forms may cause mechanical irritation. Firefighting requires Class D extinguishers for metal fires; water contact may produce hydrogen gas.
B2B Procurement Guide
Industrial buyers should specify: 1) Purity level (standard 3N or high-purity 4N-5N) 2) Physical dimensions and tolerance 3) Backing plate requirements (copper, molybdenum) 4) Surface roughness (typically <5μm) 5) Certification (traceable lot analysis). Lead times for custom targets often exceed 8 weeks. Consider bonded targets for thermal stress applications. Major suppliers provide metallurgical reports and can customize packaging for oxygen-sensitive shipments. Sample testing is recommended before bulk orders.
