Description

Gadolinium is a silvery-white, malleable, and ductile rare earth metal belonging to the lanthanide series. Its unique magnetic and neutron-absorbing properties make it a critical material for advanced technological and medical applications. This high-purity element is essential for manufacturers and researchers in the medical imaging, nuclear, and electronics industries seeking reliable, high-performance materials.

Application

• Magnetic Resonance Imaging (MRI) Contrast Agents: Gadolinium(III) chelates are the active component in most intravenous MRI contrast media, enhancing image clarity.
• Nuclear Reactor Control Rods: Utilized for its high neutron absorption cross-section to control nuclear fission reactions.
• Data Storage & Electronics: A key component in magneto-optical recording media (e.g., GdFeCo alloys) and semiconductor doping.
• Phosphors & Luminescence: Used in X-ray intensifying screens, CRT displays, and LED phosphors to produce specific colors.
• Industrial & Research Catalysts: Employed in petroleum cracking and various organic synthesis reactions.
• Metallurgical Additive: Improves the workability, high-temperature oxidation resistance, and mechanical properties of alloys like iron, chromium, and magnesium.

Quality Control

Our Gadolinium is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards, typically ranging from 99.9% (3N) to 99.999% (5N) depending on the grade. Certificates of Analysis (COA) detailing purity and trace metal impurities are provided with every shipment to guarantee consistency and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon) in a cool, dry, well-ventilated area away from incompatible materials. Due to its pyrophoric nature in powder form, appropriate safety measures must be observed.
