Description

Gadolinium-153 is a stable, non-radioactive isotope of the rare earth element gadolinium, identified by CAS No. 14276-65-4. This high-purity material is critical for applications requiring precise isotopic composition and minimal neutron absorption cross-section. It is essential for manufacturers and researchers in the nuclear, scientific instrumentation, and advanced materials sectors.

Application

• Neutron Absorption Control: Used as a burnable poison or neutron absorber in nuclear reactor control rods and shielding due to its high thermal neutron capture cross-section.
• Scientific Research & Calibration: Serves as a reference standard and target material in nuclear physics research, particle accelerator experiments, and detector calibration.
• Medical Device Manufacturing: Employed in the production of specialized components for magnetic resonance imaging (MRI) and other diagnostic equipment.
• Advanced Alloys & Metallurgy: An additive for creating specialized gadolinium-based alloys with unique magnetic or physical properties.
• Optical & Phosphor Materials: A dopant in the synthesis of crystals, glasses, and phosphors for lasers and scintillation detectors.
• Chemical Synthesis & Catalysis: Acts as a precursor or catalyst in specialized organic synthesis and industrial chemical processes.

Quality Control

Our Gadolinium-153 is produced and handled under stringent quality management protocols. Each batch is analyzed to confirm isotopic purity, chemical purity, and the absence of specific metallic impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic abundance, assay, and trace element content is provided to ensure compliance with your technical specifications and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., argon) is recommended for optimal preservation of the metallic form.
