In recent years, with the continuous advancement of science and technology, the application scope of rare earth elements has been expanding, with gadolinium emerging as a focus of attention. As a member of the rare earth series, gadolinium, with its unique properties and versatility, plays a significant role in the fields of medicine, industry, and technology.

The physical and chemical properties of gadolinium

Physical Properties

• Flammable
• Better ductility, easy to process in various forms, including Gadolinium Sheet/Foil/Disc/Plate, etc.
• Ferromagnetic at room temperature, superconducting near absolute zero.

Chemical Properties

• It exhibits high chemical reactivity, readily undergoing chemical reactions with air, water, and halides to yield corresponding higher oxidation state gadolinium derivatives.
• It is relatively stable in dry air but loses its luster in humid air, forming a thin film of gadolinium oxide on the surface.

What is gadolinium used for?

Medical Field

• MRI Contrast Agent: Gadolinium compounds are widely used as contrast agents in magnetic resonance imaging (MRI), enhancing the contrast of MRI images to aid doctors in more accurately diagnosing and observing diseases.
• Angiography: Gadolinium-based contrast agents can be used in angiography to help detect vascular narrowing, occlusions, or abnormalities.
• Tumor Diagnosis: In tumor diagnosis, gadolinium-based contrast agents can highlight the differences between tumor tissue and surrounding normal tissue, aiding in the assessment of tumor location, size, and characteristics.

Materials Field

• Optical Materials: Gadolinium compounds can be used to fabricate various optical materials such as fluorescent materials, laser crystals, and optical glasses, for use in optical devices and laser technologies.
• Coating materials: Cerium Gadolinium (Ce/Gd) sputtering targets and Gadolinium Oxide (Gd2O3) evaporation material are used in deposition processes including semiconductor deposition, chemical vapor deposition (CVD), and physical vapor deposition (PVD).
• Magnetic Materials: Due to the magnetic properties of gadolinium compounds, they can be utilized in the fabrication of magnetic materials such as magnetic recording materials and magnetic sensors.

Nuclear Field

• Nuclear Reactor Control Material: Gadolinium compounds can be used as control materials in nuclear reactors to regulate the rate of nuclear reactions and heat release.
• Neutron Absorber: Gadolinium compounds have high neutron absorption cross-sections and can be used as neutron absorbers to regulate neutron flux and reactor performance in nuclear reactors.
• Nuclear Fuel Preparation: Gadolinium compounds can be utilized in the extraction and separation steps of rare earths during the preparation of nuclear fuels.

How is Gadolinium used?

• Safety: When using gadolinium compounds, strict adherence to safety procedures is necessary to avoid skin contact and inhalation.
• Dosage Control: In medical applications, proper control of gadolinium contrast agent dosage is crucial to avoid potential side effects and allergic reactions.
• Renal Function Monitoring: After using gadolinium contrast agents, close monitoring of the patient's renal function is required, especially for those with impaired kidney function.
• Allergic Reactions: Some individuals may experience allergic reactions to gadolinium contrast agents, so careful assessment of the patient's allergy history is necessary before use.
• Waste Disposal: Used gadolinium contrast agents and waste materials should be disposed of properly according to regulations to prevent environmental contamination.

Gadolinium holds vast prospects in medicine, industry, and technology. With technological advancements, its applications will continue to expand and deepen, bringing more benefits to humanity.
