• The Melting point of Zirconium is /K 2128 or
  1855 C (3371 F)
• The color of Zirconium is gray
• The conductivity of Zirconium is 0.0236 106/cm
• The freezing point of Zirconium is 437 degrees
  celsius

• The five uses of Zirconium are
• The metal is used in the nuclear industry for
  cladding fuel elements since it has a low
  absorption cross section for neutrons.
• The metal is also used as an alloying agent in
  steel and for making surgical appliances
• Zirconium is used as a "getter" in vacuum tubes,
  in flash bulbs for photography, in explosive
  primers, and in lamp filaments.
• The oxide in Zirconium is used
• for laboratory crucibles that will withstand heat
  shock
• The metal superconducts at low temperatures and
  zirconium/niobium alloys are used to make
  superconductor magnets.

Facts about Zirconium

• Zirconium was founded by Martin Heinrich Klaproth
  in Berlin,Germany in the year 1789
• Zirconium used to be called Zircon
• The impure metal was first isolated by Jöns
  Jacob Berzelius in 1824 who heated a mixture of
  potassium and potassium zirconium fluoride
  together in an iron tube. Pure zirconium was
  first prepared in 1914.

• The finely divided metal can ignite spontaneously
  in air, especially at elevated temperatures.
• Hafnium is invariably found in zirconium ores,
  and the separation is difficult
