yttrium, Y, atomic number 39(noun)
a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys
A metallic chemical element (symbol Y) with an atomic number of 39.
Origin: From Ytterby, (literally, "outer village") a town in Sweden.
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
Origin: [NL., from Ytterby, in Sweden. See Erbium.]
Yttrium is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and it has often been classified as a "rare earth element". Yttrium is almost always found combined with the lanthanides in rare earth minerals and is never found in nature as a free element. Its only stable isotope, 89Y, is also its only naturally occurring isotope. In 1787, Carl Axel Arrhenius found a new mineral near Ytterby in Sweden and named it ytterbite, after the village. Johan Gadolin discovered yttrium's oxide in Arrhenius' sample in 1789, and Anders Gustaf Ekeberg named the new oxide yttria. Elemental yttrium was first isolated in 1828 by Friedrich Wöhler. The most important use of yttrium is in making phosphors, such as the red ones used in television set cathode ray tube displays and in LEDs. Other uses include the production of electrodes, electrolytes, electronic filters, lasers and superconductors; various medical applications; and as traces in various materials to enhance their properties. Yttrium has no known biological role, and exposure to yttrium compounds can cause lung disease in humans.
Chambers 20th Century Dictionary
it′ri-um, n. a rare metal obtained as a blackish-gray powder, and contained in a few minerals in which there are usually also present compounds of one or more other rare metals, such as cerium, didymium, erbium, and lanthanum.—n. Ytt′ria, its oxide, a yellowish-white powder.—adjs. Ytt′ric; Yttrif′erous; Ytt′rious.—ns. Ytt′ro-cē′rite, a violet mineral found embedded in quartz, a fluoride of yttrium, cerium, and calcium; Ytt′ro-col′umbite, -tan′talite, a brownish mineral found at Ytterby, a tantalate of yttrium, uranium, and iron, with calcium. [From Ytterby, a town in Sweden, where it was first discovered.]
The Nuttall Encyclopedia
a rare metal always found in combination with others, and is a blackish-gray powder; the oxide of it, yttria, is a soft whitish powder, and when ignited glows with a pure white light.
U.S. National Library of Medicine
An element of the rare earth family of metals. It has the atomic symbol Y, atomic number 39, and atomic weight 88.91. In conjunction with other rare earths, yttrium is used as a phosphor in television receivers and is a component of the yttrium-aluminum garnet (YAG) lasers.
