Description

Praseodymium is a soft, silvery, malleable, and ductile rare earth metal belonging to the lanthanide series. Its unique electronic configuration makes it a critical component in advanced materials, particularly for its exceptional magnetic and optical properties. This element is essential for manufacturers in the permanent magnet, specialty glass, catalysis, and metallurgical alloy industries seeking to enhance product performance.

Application

• Permanent Magnets: A key dopant in neodymium-iron-boron (NdFeB) magnets to improve temperature stability and coercivity for use in electric vehicle motors, wind turbines, and high-performance speakers.
• Specialty Glass & Ceramics: Used to produce didymium glass for protective goggles (welding/glassblowing) and to impart a clean yellow color in ceramics and decorative glass.
• Catalysts: Employed in automotive catalytic converters and petroleum cracking catalysts due to its ability to store and release oxygen.
• Metallurgical Alloys: Added to magnesium alloys to create high-strength materials for aerospace applications and to improve the workability of other metals.
• Phosphors & Lighting: Used in phosphors for trichromatic lighting, color television tubes, and fluorescent lamps.
• Fiber Optics: Serves as a dopant in fiber optic amplifiers to boost signal strength in telecommunications networks.
• Carbon Arc Lighting: Provides a strong, steady light source in studio lighting and projection systems.

Quality Control

Our Praseodymium is produced and handled under strict quality management protocols. Each batch is analyzed to ensure it meets high-purity standards, typically ranging from 99% to 99.99% (REO) based on grade. We provide comprehensive Certificates of Analysis (COA) detailing purity and trace metal impurities, supporting traceability and compliance for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), it must be stored under an inert gas (argon or nitrogen) in a cool, dry, well-ventilated area. For long-term storage, keep at room temperature (15-25°C) in a moisture-free environment. Isolate from strong acids and oxidizers.
