Tarix
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.

Applications
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.
