Use
Gadolinium’s main use is based on its ability to absorb neutrons, thus making it ideal as aneutron-shielding and neutron-absorbing metal. It is also used as an alloying agent for steel andother metals to make the metals more workable and to be able to withstand low temperatures. Gadolinium is used in the manufacture of electronics and can be combined with yttriumto make garnets used in microwaves. Gadolinium is used as a catalyst to speed up chemicalreactions, and to activate phosphor compounds in TV screens and cast filaments in electricaldevices. It is also used in high-temperature furnaces. Gadolinium is paramagnetic at normalroom temperatures (weaker than ferromagnetic) and becomes strongly ferromagnetic at verycold temperatures.
