Product Description Lanthanum Rare Earth Element CAS 7439-91-0Product Name: Lanthanum powderCas No: Lanthanum Purity: 99%minAppearance: gray powderParticle size: 100-200 mesh Can be supplied according to customer requirements.Product ParametersLanthanum (La), a soft, silvery-white rare earth metal with the atomic number 57, is a critical material driving innovation acrosselectronics, energy, and industrial applications. With its unique chemical reactivity, high thermal stability, and exceptional opticalproperties, lanthanum serves as a cornerstone in modern high-tech industries. Its molecular formula La, molecular weight 138.91g/mol, and CAS number 7439-91-0 make it a well-characterized and indispensable element for cutting-edge solutions. Feature1. High Reactivity & Catalytic EfficiencyActs as a powerful reducing agent and catalyst in petroleum refining, automotive exhaust systems, and hydrogenation reactions.Enhances reaction rates and process efficiency in chemical synthesis.2. Optical & Electronic ExcellenceKey component in lanthanum-doped optical glass (e.g., camera lenses, telescopes) for superior light refraction and UV/IR absorption.Used in phosphors for lighting, displays, and X-ray intensifying screens.3. Energy Storage InnovationCritical for nickel-metal hydride (NiMH) batteries as a hydrogen-absorbing alloy, enabling high energy density and longevity.Explored in next-generation solid-state batteries and fuel cell technologies.4. Thermal StabilityWithstands extreme temperatures in aerospace and nuclear applications (e.g., thermal barrier coatings, reactor components).Lowers melting points in glass and ceramic production, improving manufacturability.5. High Purity & CustomizabilityAvailable in purities up to 99.99% (4N) for precision applications.Compatible with alloying, thin-film deposition, and nanotechnology processes.Product ApplicationApplication1. Electronics: Capacitors, semiconductors, and OLED displays.2. Energy: Battery anodes, hydrogen storage systems, and solar cell coatings.3. Automotive: Catalytic converters, sensors, and hybrid vehicle components.4. Optics: High-refractive-index lenses, laser crystals, and fiber optics.5. Industrial: Polishing powders (CMP), steel additives, and corrosion-resistant alloys.This powder is produced in spherical form, which makes it highly suitable for applications like additive manufacturing (3D printing),thermal spraying, and powder metallurgy. Its spherical shape ensures excellent flowability and packing density, which are critical forprecision manufacturing processes.Welcome to contact us to get complete COA.Shanghai Lonwin Chem is a leading manufacturer and supplier of chemicals in China.We develop,produce and distribute high quality pharmaceuticals, intermediates, special chemicals and other fine chemicals.
