Description
A rare earth metallic element found in the minerals samarskite, gadolinite, monazite, and xenotime. First separated in 1880, gadolinium is a soft, silver-gray, shiny metal. It is primarily used in neutron shielding, as a phosphor activator, and as an oxygen Scavenger. Gadolinium is also used to produce gadolinium-iron garnets that control microwave frequencies.
