What’s in a name? Named after the mineral zircon, which originates from the Persian word for gold-like, zagun. Pronounced as zer-KO-ni-em.
Discovery Discovered in 1789 by Martin Klaproth in Germany. Discovered while studying the compound jargon (ZiSiO_4_) Was first isolated by the Swedish Chemist Jons Jacob Berzelius Klaproth Berzelius

Availability 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
Kroll Process 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.
Uses of Zirconium 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
More Uses… 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.
