yttrium
\yt"tri*um\ (?), n. [nl., from ytterby, in sweden. see erbium.] (chem.) 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, 89. [written also ittrium.]
note: 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.
