Gadolinium Gadolinium is a member of the lanthanide group of elements, and is obtained from the same sources as europium. It is a silvery white metal which is ductile and malleable. It is stable in a dry atmosphere but forms an oxide coating when exposed to moist air. It reacts slowly with water and is soluble in acids. Gadolinium has limited uses as a pure metal, but when alloyed with chromium, iron or similar metals, the resulting alloys have improved workability and corrosion resistance. Due to its magnetic properties, gadolinium is used in the manufacture of magnets, recording heads and electrical components.
