Description

Samarium-148 is a stable, non-radioactive isotope of the rare earth element samarium, distinguished by its unique nuclear properties. This high-purity material is critical for advanced research and development in fields requiring precise isotopic composition. It is primarily utilized by the nuclear science, materials research, and specialized electronics industries for applications such as neutron absorption studies and the fabrication of advanced alloys.

Application

• Neutron Absorption and Shielding: Used in nuclear reactors and research facilities as a component in control rods or shielding materials due to its high thermal neutron capture cross-section.
• Nuclear Science Research: Serves as a target material or a stable isotopic tracer in fundamental nuclear physics experiments and reaction studies.
• Metallurgy and Advanced Alloys: Incorporated into specialty alloys to modify mechanical properties, corrosion resistance, or magnetic characteristics for high-performance applications.
• Reference Standards: Employed in the production of certified reference materials (CRMs) for calibrating analytical instruments like mass spectrometers.
• Electronics and Semiconductors: Investigated for use in specialized dopants or thin-film layers within next-generation electronic and optoelectronic devices.
• Geological and Cosmochemical Dating: Utilized in the Samarium-Neodymium (Sm-Nd) dating method to determine the age of rocks and meteorites.

Quality Control

Our Samarium-148 is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analysis to verify isotopic purity, chemical purity, and trace metal content. Certificates of Analysis (COA) detailing isotopic abundance (typically >99% 148Sm) and impurity profiles are provided to ensure material integrity for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, this material should be stored under an inert atmosphere (e.g., argon) in a cool, dry place. Recommended storage temperature is 15-25°C. Handle and store away from incompatible materials.
