Praseodymium Metal (Pr) | High-Purity Rare Earth Element for Alloys & Magnets
Praseodymium Metal is a reactive rare-earth element primarily utilized as a key alloying additive in high-performance NdFeB (Neodymium-Iron-Boron) permanent magnets and high-temperature magnesium alloys. Produced via molten salt electrolysis and vacuum distillation, our praseodymium metal ingots feature low non-rare-earth impurity profiles, engineered for demanding metallurgical and electronic applications.
Key Features
Controlled Impurity Profile
Minimized interstitial elements (O, N, C) achieved through vacuum induction melting.
Metallurgical Consistency
Uniform grain structure ensuring predictable dissolution rates in master alloy preparation.
Oxidation Mitigation
Vacuum-sealed under high-purity argon in multi-layer barrier packaging inside steel drums to prevent atmospheric degradation prior to industrial processing.

Quality Control & Manufacturing Capabilities
Production Process: Molten salt electrolysis of high-purity rare earth oxides followed by multi-stage vacuum distillation to remove volatile non-rare earth impurities.
Analytical Testing: Every production lot is verified via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for trace metallic impurities and Inert Gas Fusion for interstitial gases (O/N).
Traceability: Full lot backward traceability from raw material oxide feed to the final packaged ingot, supported by an independent Certificate of Analysis (COA) shipped with every order.
Packaging & Shipping
Primary Packaging: Hermetically sealed under high-purity argon gas in barrier-layered polyethylene bags.
Secondary Packaging: Heavy-duty steel drums lined with impact-absorbing material, net weight 50kg or 100kg per drum.
Logistics & Compliance: Handled strictly via certified dangerous goods logistics in compliance with international maritime (IMDG) and air (IATA) transport regulations for reactive rare-earth metals.
Documentation
Technical Downloads: Typical Certificate of Analysis (COA) and Safety Data Sheet (SDS) available upon formal technical request or inquiry submission.
Compliance Support: Certificate of Origin and REACH compliance documentation provided with every commercial shipment.
MOQ & Lead Time
Minimum Order Quantity (MOQ): 100 kg.
Standard Lead Time: 15 to 25 business days for standard purity grades; custom cuts or specific impurity caps require technical review (additional 10 business days).
FAQ
Q: How is the metal protected against oxidation during international transit?
A: Ingots are packed under an argon atmosphere in heavy-duty hermetically sealed containers to completely eliminate moisture and oxygen exposure before opening.
Q: Can you accommodate customized impurity caps for specific co-impurities (e.g., Neodymium)?
A: Yes. Utilizing multi-stage separation and distillation, we adjust individual rare earth tolerances based on your specific magnetic or metallurgical performance requirements.
Q: What export documentation accompanies the shipment?
A: Each shipment includes a lot-specific COA, commercial invoice, packing list, and dangerous goods declaration complying with international export protocols.
