Description
Lanthanum is a soft, malleable, and silvery-white rare earth metal that serves as a foundational material for numerous high-tech and industrial processes. Its unique chemical properties, particularly its strong affinity for oxygen and sulfur, make it an essential component for refining, catalysis, and advanced material synthesis. This product is critical for manufacturers and researchers in the optical glass, petroleum refining, battery technology, and electronics sectors who require a reliable source of high-purity lanthanum metal.
Application
- Optical Glass & Lenses: A key component in specialty glasses, including camera and telescope lenses, to improve refractive index and reduce dispersion.
- Catalysts for Petroleum Refining: Used in fluid catalytic cracking (FCC) catalysts to enhance gasoline yield and reduce sulfur content in fuels.
- Hydrogen Storage Alloys: An important alloying element in nickel-metal hydride (NiMH) rechargeable batteries for improved capacity and cycle life.
- Electronic Ceramics & Capacitors: Employed in the production of dielectric materials for multilayer ceramic capacitors (MLCCs) and other electronic components.
- Steel & Alloy Additive: Acts as a scavenger for impurities like oxygen and sulfur, improving the ductility and workability of steels and superalloys.
- Phosphors & Lighting: Used in phosphor compounds for fluorescent lamps, X-ray intensifying screens, and cathode-ray tubes.
- Water Treatment: Applied as a phosphate binder in wastewater treatment to control algal growth.
- Research & Development: Serves as a starting material for synthesizing various lanthanum compounds and for fundamental research in material science.

Quality Control
Our lanthanum metal is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets the required purity standards, typically ranging from 99% to 99.99% (3N to 4N), depending on the grade. We provide traceable Certificates of Analysis (COA) detailing assay and impurity profiles. Our quality systems are designed to support applications requiring consistency and reliability, from industrial catalysis to advanced material research.
Storage
Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, lanthanum metal must be stored under an inert atmosphere such as argon or in mineral oil to prevent surface oxidation and degradation. Store in a cool, dry, well-ventilated area away from incompatible materials. Recommended storage temperature is 15-25°C.
