Description

Dysprosium Dichloride is an inorganic salt of the rare earth element dysprosium, widely utilized as a specialized precursor in advanced material synthesis. Its primary commercial value lies in its role as a high-purity starting material for producing dysprosium-based phosphors, catalysts, and specialty alloys. This compound is essential for manufacturers and research institutions in the fields of magnet production, optical materials, and chemical vapor deposition (CVD).

Application

• Rare Earth Magnet Manufacturing: A key precursor for synthesizing dysprosium-containing alloys used in high-performance neodymium-iron-boron (NdFeB) magnets to enhance coercivity and thermal stability.
• Phosphor and Optical Material Production: Serves as a starting material in the synthesis of dysprosium-doped crystals and glasses for lasers, lighting, and radiation detection applications.
• Chemical Vapor Deposition (CVD): Used as a volatile source for depositing dysprosium oxide (Dy₂O₃) thin films in semiconductor and optical coating processes.
• Catalyst Research & Development: Employed in the preparation of specialized catalysts for organic synthesis and polymerization reactions.
• Specialty Alloy Production: Acts as a doping agent to modify the properties of magnesium and other non-ferrous alloys.
• Academic & Industrial R&D: A fundamental reagent for research in inorganic chemistry, materials science, and solid-state physics.

Quality Control

Our Dysprosium Dichloride is produced under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a series of analytical techniques including Inductively Coupled Plasma (ICP) and titration methods. A Certificate of Analysis (COA) detailing purity, trace metal content, and other critical parameters is provided with each shipment to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place under an inert atmosphere (e.g., argon or nitrogen) to prevent moisture absorption and hydrolysis. Recommended long-term storage temperature is 15-25°C. Keep the container tightly sealed in a desiccator when not in use.
