Frequently asked questions
What is gadolinium used for?
Gadolinium is used in permanent magnets, magnetic refrigeration and fluorescent lamps. Permanent magnets: alloys containing neodymium, samarium, gadolinium, dysprosium or praseodymium (USGS, 2002); the EU lists gadolinium among the rare earths for permanent magnets.
Which country produces the most gadolinium?
USGS does not report gadolinium separately; China produced the most rare earths of any country in 2025, an estimated 270,000 t (69%) of the world's 390,000 t of rare earth oxide equivalent.
Is gadolinium a critical mineral?
Yes. Gadolinium is on all four official critical minerals lists: the US, EU, Australian and Canadian. Gadolinium was already on the 2022 US list and stays on the final 2025 list of 60 minerals. US net import reliance for gadolinium in 2025 was 67% for rare earth compounds and metals as a group.
How much does gadolinium cost?
USGS reports the average 2025 price of gadolinium at $30/kg (gadolinium oxide, 99.99% minimum, average; +7% on 2024).
