Overview
Dysprosium oxide powder (Dy₂O₃) is a rare earth compound derived from dysprosium, a lanthanide element. It is prized for its high thermal neutron absorption cross-section and paramagnetic properties. The powder form is particularly useful in industrial applications due to its uniform particle size and reactivity. As a critical material in high-tech sectors, dysprosium oxide is subject to supply chain fluctuations. It is typically produced through calcination of dysprosium salts or via solvent extraction from monazite sands. Global production is concentrated in China, the U.S., and Australia.
Physical and Chemical Properties
Dysprosium oxide powder is chemically stable under normal conditions but reacts with strong acids to form dysprosium salts. Its high melting point (2,410°C) makes it suitable for high-temperature applications. The material exhibits paramagnetism, which is leveraged in specialized alloys and electronic components. The powder is insoluble in water but dissolves in mineral acids like hydrochloric or nitric acid. Its density (7.81 g/cm³) and white-to-yellow appearance vary slightly depending on purity and processing methods. Particle sizes typically range from 1 to 10 microns for most industrial grades.
Main Applications
In nuclear reactors, dysprosium oxide is used as a neutron absorber in control rods due to its high neutron capture efficiency. The electronics industry employs it in phosphors for LEDs and as a dopant in magnetostrictive alloys for sensors and actuators. Advanced ceramics incorporate Dy₂O₃ to improve thermal stability and mechanical strength. It also serves as a catalyst in organic synthesis and a raw material for producing metallic dysprosium. Emerging applications include data storage devices and laser materials.
Safety and Storage
While dysprosium oxide is not highly toxic, inhalation of fine powder can cause respiratory irritation. Workers should use NIOSH-approved respirators, gloves, and eye protection. The powder should be stored in airtight containers with desiccants to prevent moisture absorption. Avoid contact with strong acids, which can produce hazardous dysprosium salts. Spills should be contained and cleaned with dry methods; water should not be used. Dispose of waste in accordance with local regulations for rare earth compounds.
B2B Procurement Guide
When sourcing dysprosium oxide powder, prioritize suppliers with ISO 9001 certification and traceable rare earth supply chains. Key specifications to verify include purity (≥99.9% for most applications), particle size distribution (measured via laser diffraction), and absence of heavy metal contaminants. Bulk purchases (100kg+) often qualify for discounts, but consider just-in-time delivery to minimize storage costs. Spot prices fluctuate with rare earth market trends; long-term contracts may offer stability. Always request material safety data sheets (MSDS) and certificates of analysis (CoA).
