gadolinium

/ găd′l-ĭn′ē-əm /

1. A silvery-white, malleable, ductile metallic element of the lanthanide series that has seven natural isotopes and 11 artificial isotopes. Two of the natural isotopes, Gd 155 and Gd 157, are the best known neutron absorbers. Gadolinium is used to improve the heat and corrosion resistance of iron, chromium, and various alloys and in medicine as a contrast medium for magnetic resonance imaging and as a radioisotope in bone mineral analysis. Atomic number 64; atomic weight 157.25; melting point 1,312°C; boiling point approximately 3,000°C; specific gravity from 7.8 to 7.896; valence 3.
