Description

Samarium is a lustrous, silvery-white rare earth metal belonging to the lanthanide series, known for its significant paramagnetic properties. Its unique electronic configuration makes it a critical component in the production of powerful permanent magnets, such as Samarium-Cobalt (SmCo) alloys, which are essential for high-performance applications. This metal is vital for manufacturers and R&D facilities in the electronics, aerospace, defense, and nuclear industries, where its specific magnetic and neutron absorption characteristics are leveraged.

Application

• Permanent Magnets: A key constituent in Samarium-Cobalt (SmCo) magnets, offering high magnetic strength and thermal stability for motors, sensors, and aerospace guidance systems.
• Nuclear Reactors: Used as a neutron absorber in control rods due to its high thermal neutron capture cross-section.
• Catalysts: Employed in specific organic synthesis and dehydrogenation processes within the chemical manufacturing sector.
• Specialty Alloys: Added to magnesium and aluminum alloys to improve high-temperature strength and creep resistance.
• Electronics & Optoelectronics: Used in dopants for calcium fluoride crystals in lasers and in infrared-absorbing glass.
• Research & Development: Serves as a starting material for synthesizing various samarium compounds and for fundamental studies in material science.

Quality Control

Our samarium metal is produced under stringent process controls to ensure high purity and batch-to-batch consistency. Quality is verified through advanced analytical techniques including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Glow Discharge Mass Spectrometry (GDMS) for trace impurity analysis. A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical form is provided with each shipment to meet the exacting requirements of advanced manufacturing and research.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature of being easily oxidized, samarium metal must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area. For long-term storage, maintain at room temperature (15-25°C) in a moisture-free environment to prevent surface oxidation and degradation.
