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.
