Overview
Dysprosium sputtering targets are high-purity metallic materials used in physical vapor deposition (PVD) processes to create thin film coatings. As a rare earth element, dysprosium offers unique magnetic and optical properties that make it valuable for specialized applications. These targets are typically manufactured through vacuum melting and precision machining to achieve the required purity (commonly 99.9% or higher) and dimensional specifications. In industrial applications, dysprosium targets are bonded to backing plates for thermal management during the sputtering process. The targets are available in various standard sizes and shapes (circular, rectangular) to accommodate different deposition systems. Quality control measures including ultrasonic testing ensure defect-free surfaces for consistent film deposition.
Physical and Chemical Properties
Dysprosium is a lustrous, silvery rare earth metal with hexagonal close-packed crystal structure at room temperature. It demonstrates excellent thermal neutron absorption cross-section and maintains strong magnetic properties at high temperatures, making it particularly useful for specialized coatings. The metal is relatively stable in dry air but oxidizes slowly in moist environments. Key parameters for sputtering targets include density (typically >95% of theoretical density), grain size (usually <100μm), and purity level (3N to 4N being most common). The thermal conductivity of dysprosium is approximately 10.7 W/m·K, which affects heat dissipation during sputtering. Electrical resistivity is about 926 nΩ·m at 25°C, influencing plasma generation in the deposition process.
Main Applications
The primary use of dysprosium sputtering targets is in the production of thin films for data storage technologies, particularly in magneto-optical recording media where its high magnetic anisotropy is crucial. These targets are also employed in semiconductor fabrication for creating specialized diffusion barriers and in research laboratories studying rare earth thin film properties. In the optical industry, dysprosium films find application in infrared absorbing coatings and laser components. The nuclear sector utilizes dysprosium-containing films for neutron detection and shielding applications. Emerging applications include spintronic devices and advanced magnetic sensors that leverage dysprosium's unique electronic configuration.
Safety and Storage
Dysprosium metal presents moderate health hazards in powder or dust form, requiring proper handling procedures. The material should be stored in airtight containers under argon atmosphere to prevent oxidation. Work areas should have adequate ventilation when machining or handling targets to avoid accumulation of fine particles. Personal protective equipment including nitrile gloves and safety goggles should be worn during handling. In case of fire, use Class D extinguishers for metal fires. Spent targets should be collected for proper recycling as rare earth materials have significant reclaim value. Storage temperature should be maintained at room temperature with controlled humidity below 40% RH.
B2B Procurement Guide
When sourcing dysprosium sputtering targets, buyers should specify critical parameters including purity (3N5 or 4N typical), dimensions (diameter/thickness with tolerances), bonding requirements (if applicable), and surface finish (usually <1μm roughness). Reputable suppliers should provide material certification with traceable lot numbers and complete chemical analysis. Lead times can vary from 4-12 weeks depending on specifications and market availability of high-purity dysprosium. Consider vendor capabilities in custom machining and bonding services. For high-volume purchases, negotiate pricing based on long-term contracts as rare earth prices fluctuate. Quality verification should include third-party testing for composition and microstructure analysis.
