Ittrium
(gcide) | Ittrium \It"tri*um\ ([i^]t"tr[i^]*[u^]m), n. [NL.]
See Yttrium.
[1913 Webster] |
ittrium
(gcide) | 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 number 39. Atomic weight,
88.9. [Written also ittrium.]
[1913 Webster +PJC]
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.
