Where is Gadolinium Found?

Gadolinium is found in several other minerals, including monazite and bastnasite, both of which are commercially important. With the development of ion-exchange and solvent extraction techniques, the availability and prices of gadolinium and the other rare-earth metals have greatly improved. The metal can be prepared by the reduction of the anhydrous fluoride with metallic calcium.

What is Gadolinium Used For?

Gadolinium yttrium garnets are used in microwave applications and gadolinium compounds are used as phosphors in color television sets.

Gadolinium is unique for its high magnetic movement and for its special Curie temperature lying just at room temperature, meaning it could be used as a magnetic component that can sense hot and cold.
