Zirconium is a chemical element; it has symbol Zr and atomic number 40. First identified in 1789, isolated in impure form in 1824, and manufactured at scale by 1925, pure zirconium is a lustrous transition metal with a greyish-white color that closely resembles hafnium and, to a lesser extent, titanium.

Crystal Structure. Simple Hexagonal. 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.
Zircon (zirconium silicate, ZrSiO 4) is a natural gemstone and synthetic cubic zirconia (zirconium dioxide, ZrO 2) is produced as a low-cost substitute for diamond. Zirconium based catalysts are used in amination, hydrogenation, isomerization and oxidation reactions.
