Description
Overview
Gadolinium, a silvery-white rare earth metal, exhibits relative stability in dry air but oxidizes when exposed to moisture, requiring careful storage and handling, and is typically processed into forms like ingots, powder, or gadolinium oxide for various industrial applications. Extracted primarily from bastnäsite and monazite ores through intricate separation and refining techniques, gadolinium is a vital material in advanced technologies. Renowned for its high magnetic susceptibility and exceptional neutron absorption capabilities, it plays a critical role in medical imaging as a key component in MRI contrast agents, enhancing the visibility of internal structures, and in nuclear applications, such as control rods in reactors for improved safety. Its unique properties also make it valuable in magnetic refrigeration and high-performance alloys. Gadolinium’s growing importance in healthcare and energy sectors, combined with its potential for recycling, underscores its role as a sustainable and strategic resource in the technology metals market.

Market outlook
Gadolinium’s demand is driven by medical imaging and nuclear applications. Gadolinium oxide prices are around $20–$40 per kg as of early 2025, with China dominating supply. The market is expected to grow with advancements in MRI technology and magnetic refrigeration, though environmental concerns about gadolinium in medical waste may impact future use.
