High-Purity Lanthanum Metal
Lanthanum Metal is a soft, malleable, and highly reactive rare earth element primarily utilized as an alloying additive, catalyst component, and raw material for advanced functional materials. Produced via molten salt electrolysis, our lanthanum metal ingots and chunks are processed and packaged under controlled inert environments to minimize atmospheric oxidation. Designed for industrial metallurgy, high-performance battery production, and specialty glass manufacturing, it delivers tightly controlled trace impurities to meet demanding metallurgical standards and global compliance frameworks including EU REACH and US TSCA.
Key Features
High Metallurgical Purity: Available in standard purities up to 99.9% (La/TREM) with total rare earth purity exceeding 99.95%.
Controlled Trace Impurities: Low interstitial gas content and strictly monitored non-rare earth metallic impurities (Fe, Ca, Mg, Si) verified via advanced spectrometry.
Inert Packaging: Vacuum-sealed in aluminized foil under high-purity argon or submerged in mineral oil to prevent premature surface oxidation during transit.
Flexible Forms: Supplied as broken ingots, cut pieces, and custom rods tailored to specific induction melting or alloying processes.

Applications
Hydrogen Storage Alloys: Serves as a core base metal for AB5-type alloys used in Nickel-Metal Hydride (NiMH) rechargeable batteries.
Metallurgical Additives: Acts as a powerful deoxidizer, desulfurizer, and nodularizer in specialized steel and cast iron production to improve high-temperature mechanical properties.
Specialty Glass & Optics: Added to optical glass formulations to increase refractive index and reduce chromatic dispersion for precision camera lenses and fiber optics.
Catalysis: Utilized as a precursor for fluid catalytic cracking (FCC) catalysts in petroleum refining.
Manufacturing & Quality Control
Electrolysis & Refining: Extracted and refined via multi-stage molten salt electrolysis followed by vacuum distillation to eliminate volatile metallic impurities.
Analytical Verification: Every production lot is verified using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Glow Discharge Mass Spectrometry (GD-MS) for complete elemental tracking.
Traceability: Each shipment includes an individual Certificate of Analysis (CoA) detailing exact batch purity and impurity profiles.

Frequently Asked Questions
Q: How is the metal protected against oxidation during international shipping?
A: Lanthanum metal is highly reactive to air and moisture. We package all shipments under an argon atmosphere in hermetically sealed containers or fully immerse the material in high-purity mineral oil to ensure zero oxidation upon arrival.
Q: Can you provide custom sizes for induction melting?
A: Yes. We can cut ingots into specific chunk sizes or machine rods according to your crucible dimensions to reduce preparation time in your facility.
Q: What is the standard export procedure for rare earth metals?
A: Shipments are processed in compliance with current international rare earth export regulations, including legal export licensing and dangerous goods (Class 4.1 / 4.3 flammable solids) compliant packaging for ocean or air freight, alongside complete REACH/TSCA documentation.
