History

Zirconium was first recognized as an element by Martin Heinrich Klaproth in 1789, in Berlin, in a sample of zircon from Sri Lanka. Zirconium metal was first obtained in an impure form in 1824 by Jöns Jakob Berzelius by heating a mixture of potassium and potassium zirconium fluoride in an iron tube. Dutch scientists Anton Eduard van Arkel and Jan Hendrik de Boer discovered a method for producing high purity zirconium in 1925. From the Persian zargun, gold like

Discoverers	Martin Klaproth

Etymology (Name Origin)	From the mineral, zircon.
Pronunciation	zer-KO-ni-em (English)

Zirconium is considered to be non-toxic

The most common oxide is zirconium dioxide, also referred to as zirconia

Uses

Zirconium is mainly used as a refractory and opacifier, although it is used in small amounts as an alloying agent for its strong resistance to corrosion. Zirconium is used as to make surgical instruments and is used in steel alloys as a hardening agent. Zirconium is also used to make superconductive magnets. Used in alloys such as zircaloy which is used in nuclear applications since it does not readily absorb neutrons. Also baddeleyite is used in lab crucibles. Used in high-performance pumps and valves. Clear zircon (ZrSiO4) is a popular gemstone.

Sources

Found in many minerals such as zircon and baddeleyite.
