Medical Definition of Yttrium

1. A rare metallic element of the boron-aluminium group, found in gadolinite and other rare minerals, and extracted as a dark gray powder. Symbol Y. Atomic weight. Alternative forms: ittrium. Associated with yttrium are certain rare elements, as erbium, ytterbium, samarium, etc, which are separated in a pure state with great difficulty. They are studied by means of their spark or phosphorescent spectra. Yttrium is now regarded as probably not a simple element, but as a mixture of several substances. Origin: NL, from Ytterby, in Sweden. See Erbium. Source: Websters Dictionary (01 Mar 1998)
