Description
Gadolinium Powder Product Overview
Gadolinium (Gd) is a silvery rare earth metal that, as a powder, appears grey to dark grey. Its Curie temperature of about 20°C is close to room temperature, which gives it a strong magnetocaloric effect, and it has the highest neutron capture cross-section of any stable element.
Researchers use gadolinium as the reference material for magnetic refrigeration near room temperature. Nuclear engineers use gadolinium compounds as burnable neutron absorbers in fuel and control materials. Metallurgists add it to alloys to improve high-temperature properties, and it is a starting material for gadolinium compounds used in phosphors and MRI contrast agents.
Fine rare earth metal powders oxidize readily and can be pyrophoric, so they are shipped under inert gas. For gadolinium in oxide form, see Gadolinium Oxide; related rare earth materials include Dysprosium Oxide and Lanthanum Oxide.

⚠️ Safety & Handling: Flammable solid; fine powder may ignite spontaneously in air and reacts with water, releasing hydrogen. Handle under inert gas, keep away from water, moisture and ignition sources, and use class D fire extinguishers. Wear gloves, eye protection and dust protection. Store sealed under argon in a dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Frequently Asked Questions
Why is gadolinium used for magnetic refrigeration research?
Its Curie temperature near room temperature gives a large magnetocaloric effect at practical temperatures.
How is gadolinium powder shipped?
Sealed under argon or another inert gas, because fine rare earth powders oxidize and can ignite in air.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
