Zirconium is a transition metal that was discovered in 1789 by Martin Klaproth in Germany while studying the compound jargon. It has 40 protons, 51 neutrons, and is a solid grayish element at room temperature. Zirconium is commonly obtained through the Kroll Process, which is the reduction of zirconium chloride with magnesium. Its primary uses include research due to corrosion resistance, as an alloying agent in steel, and in high-performance pumps and valves.

2.  Named after the mineral zircon, which
originates from the Persian word for gold-like,
zagun.
 Pronounced as zer-KO-ni-em.

6.  Zirconium doesn’t
occur in concentrated
deposits, but can be
found in deposits of
the mineral zircon.
These deposits can be
found in streambeds,
ocean beaches, or old
lake beds

7.  Zirconium is obtained through a process
known as the Kroll Process.
 Essentially is the reduction of chloride with
magnesium.
 This is the way most of the Zirconium in the
world is produced.

8. PRIMARY USES SECONDARY USES
 Used in research due to its
resistance to corrosion.
 This property also allows
it to be used in high
performance pumps and
valves.
 It is also used as an
alloying agent in steel
 Photoflash bulbs
 Explosive primers
 Vacuum Tubes
 Lamp filaments

9.  As a carbonate
(Zirconium Carbonate),
its used to treat poison
ivy.
 The most popular form
of Zirconium is
Zircon(ZrSiO_4_). A
form of this is a clear,
transparent gemstone
,that can be cut to look
like diamond and is
frequently used in
jewelry.
