History

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. Named after Ytterby, a village in Sweden near Vauxholm

Discoverers	Johann Gadolin
Discovery Location	Finland
Discovery Year	1789
Etymology (Name Origin)	From the Swedish village, Ytterby, where one of its minerals was first found.
Pronunciation	IT-ri-em (English)

Exposure to yttrium compounds in humans may cause lung disease

Finely divided yttrium is very unstable in air

Uses

Yttrium is often used in alloys, increasing the strength of aluminum and magnesium alloys. Yttrium is one of the elements used to make the red color in CRT televisions. It is also used as a deoxidizer for non-ferrous metals such as vanadium. Yttrium can be used in laser systems and as a catalyst for ethylene polymerization reactions. Combined with europium to make red phosphors for color TV's. Yttrium oxide and iron oxide combine to form a crystal garnet used in radar.

Sources

Found in minerals such as monazite, xenotime, and yttria.
