Cerium Metal is a reactive rare-earth element utilized primarily as an active additive in metallurgy, non-ferrous alloy production, and chemical synthesis. Produced via molten salt electrolysis and processed under strict inert gas protection, our cerium metal ingots and chunks feature controlled low impurity profiles to meet strict industrial specifications.
- CAS Number: 7440-45-1
- Form: Ingots, chunks, or custom-cut pieces
- Standard Purity: 99.0% - 99.9% (TREM)
Key Features
Controlled Low Iron & Oxygen
Refined through multi-stage slag separation to minimize inclusion defects in downstream alloy smelting.
Inert Packaging Integrity
Vacuum-sealed in argon-filled aluminized foil or packed in mineral oil to prevent premature atmospheric oxidation.
Traceability
Every production batch is backed by a complete Inductively Coupled Plasma Mass Spectrometry (ICP-MS) elemental analysis report.

Applications
Used as a grain refiner and deoxidizer in high-strength steels and cast iron production.
Serves as a primary component in aluminum-cerium and magnesium-cerium heat-resistant alloys.
Raw material input for rare-earth master alloys and lighter flints.
Catalyst component in organic chemical reactions and petroleum cracking.
Manufacturing & Quality Control
Our manufacturing facility operates dedicated molten salt electrolysis lines equipped with real-time temperature and current regulation systems to ensure stable crystal growth.
In-House Testing
Every batch is tested using ICP-MS for metallic impurities and inert gas fusion for oxygen content.
Process Control
Slag removal and casting are conducted inside argon-purged glove boxes to eliminate moisture exposure.

Frequently Asked Questions
Q: How is the metal protected against oxidation during transit?
A: Cerium chunks are packed in mineral oil or vacuum-sealed in argon gas within steel drums to completely isolate them from moisture and oxygen.
Q: Can you supply custom sizes or cut pieces?
A: Yes. We can cut ingots into specified fragment sizes under mineral oil protection based on your furnace charging requirements.
Q: What is the typical shelf life of unopened packaging?
A: Up to 12 months when stored in a cool, dry, and well-ventilated hazardous materials warehouse without breaching the vacuum seal.
