Description

Dysprosium is a rare earth metal with the CAS number 7429-91-6, known for its exceptional magnetic properties, particularly at low temperatures. This element is a critical component in advanced materials where high-performance magnetism and thermal stability are paramount. It is essential for manufacturers in the permanent magnet, nuclear reactor control, and specialty alloy industries seeking to enhance product performance and efficiency.

Application

• Neodymium-Iron-Boron (NdFeB) Magnets: A key additive to improve coercivity and thermal stability in high-performance permanent magnets used in electric vehicles, wind turbines, and hard disk drives.
• Nuclear Reactor Control Rods: Utilized for its high neutron absorption cross-section in control rods to regulate nuclear fission reactions.
• Specialty Alloys: Incorporated into Terfenol-D and other magnetostrictive alloys for precision sensors and actuators.
• Data Storage Media: Used in the manufacturing of magneto-optical disks and other high-density data storage solutions.
• Dopant for Solid-State Lasers & Phosphors: Serves as an activator ion in laser crystals (e.g., YAG:Dy) and in phosphors for lighting and display applications.
• Metal Halide Lamps: Added to produce a bright, white light with high color rendering properties.
• Research & Development: Employed in academic and industrial R&D for studying magnetic materials and rare earth chemistry.

Quality Control

Our dysprosium is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analysis to verify purity, metallic content, and trace impurity levels, ensuring it meets the exacting standards required for advanced technological applications. A Certificate of Analysis (COA) detailing specific assay results, typically via Inductively Coupled Plasma (ICP) analysis, is provided with every shipment to guarantee supply reliability and material consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon) in a cool, dry, well-ventilated area away from incompatible materials. Dysprosium is easily oxidized and hygroscopic (moisture-sensitive). For long-term storage of fine powders, storage under an inert liquid such as mineral oil is recommended to prevent oxidation and pyrophoric risks.
