Gadolinium (Gd) is a silvery-white, malleable rare earth metal belonging to the lanthanide series. In powder form, it is widely used in various high-tech applications due to its unique magnetic, thermal, and neutron-absorbing properties. Gadolinium is primarily known for its applications in medical imaging, magnetic materials, and nuclear reactors.

Key Applications:

• Magnetic Refrigeration: Gadolinium exhibits a strong magnetocaloric effect, meaning it heats up when exposed to a magnetic field and cools down when the field is removed. This property makes it a critical material for magnetic refrigeration technology, an emerging and energy-efficient alternative to traditional gas-compression refrigeration systems.
• Magnetic Resonance Imaging (MRI): Gadolinium compounds are used as contrast agents in MRI scans to enhance image clarity and highlight abnormalities in soft tissues, organs, and blood vessels.
• Neutron Absorption in Nuclear Reactors: Gadolinium has a very high neutron capture cross-section, making it an excellent material for use as a neutron absorber in nuclear reactors. It is often used in control rods and burnable poisons in reactors to manage the fission process and regulate reactor power.
• Magnets and Magnetic Materials: Gadolinium powder is alloyed with other metals to create high-performance permanent magnets and magnetic materials for various applications, including motors, sensors, and electronic devices.
• Thermal Neutron Shields: Due to its neutron-absorbing properties, gadolinium is also used in neutron shielding for nuclear research and radiation protection.
• Gadolinium Oxide (Gd2O3) Production: Gadolinium powder is a precursor for producing gadolinium oxide, which is used in optical glass, phosphors, and ceramics.
• Other Applications:
  • Alloys: Gadolinium is used in alloys with other rare earth elements and metals to improve strength and resistance to high temperatures.
  • Phosphors: Gadolinium is used in phosphors for color television sets, X-ray intensifying screens, and LED lighting.

Features:

• Magnetocaloric Properties: Gadolinium exhibits a large magnetocaloric effect, making it highly valuable in solid-state refrigeration systems.
• Neutron Absorption: Gadolinium is one of the best materials for absorbing neutrons, making it indispensable for nuclear reactors and radiation shielding.
• Magnetic Properties: Gadolinium is strongly magnetic at low temperatures (below 20°C), with a Curie temperature of around 293 K (20°C), where it loses its ferromagnetic properties.
• Thermal Stability: Gadolinium powder has excellent thermal stability and can withstand high temperatures, making it suitable for use in nuclear and high-temperature applications.
• Chemical Reactivity: Gadolinium is relatively stable in dry air but reacts with moisture, forming gadolinium oxide (Gd2O3) on the surface.

Specifications:

Safety Considerations:

• Reactivity: Gadolinium powder is reactive, especially in moist environments, where it can form oxides. It should be stored in dry, inert conditions.
• Flammability: Gadolinium powder is flammable and poses a fire hazard when exposed to sparks or open flames. Proper storage and handling are necessary to avoid accidental combustion.
• Health Risks: Gadolinium powder can be harmful if inhaled or ingested. It is important to use proper protective equipment (gloves, masks) when handling the powder to minimize exposure.
