Zirconium - Wikipedia

Zirconium is a chemical element with symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.

Zirconium and hafnium - USGS

Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials.

ZIRCONIUM AND HAFNIUM - USGS

zirconium and hafnium are separated for certain nuclear applications. Zirconium-clad fuel rods in nuclear reactors are hafnium-free to improve reactor efficiency because hafnium is a strong absorber of thermal neutrons. At the same time, hafnium is used in reactor control rods to regulate the fission process through neutron absorption.
