Characteristic
Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element.
Phase at STP： solid
Melting point： 1585 K (1312 °C, 2394 °F)
Boiling point： 3273 K (3000 °C, 5432 °F)
Density (near r.t.)： 7.90 g/cm3
when liquid (at m.p.)： 7.4 g/cm3
Heat of fusion： 10.05 kJ/mol
Heat of vaporization： 301.3 kJ/mol
Molar heat capacity： 37.03 J/(mol·K)
Application
Gadolinium as a metal or a salt absorbs neutrons and is, therefore, used sometimes for shielding in neutron radiography and in nuclear reactors.
Like most of the rare earths, gadolinium forms trivalent ions with fluorescent properties, and salts of gadolinium(III) are used as phosphors in various applications.
