Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium (due to its having the same number of valence electrons, being in the same group, but also to relativistic effects; the expected expansion of atomic radii from period 5 to 6 is almost exactly cancelled out by the lanthanide contraction).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 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 is mainly used as a refractory and opacifier, although small amounts are used as an alloying,USGS Minerals Information: Zirconium and Hafnium,The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO 4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1.

Get PriceZirconium is used to make the cladding for uranium oxide fuel elements. As mined, zirconium contains 1-3% per cent of hafnium, which is chemically very similar, and although it is difficult to separate the two elements this has to be done for the metal used in the nuclear industry because hafnium absorbs neutrons very strongly.Corrosion of Hafnium and Hafnium Alloys,such as iron, manganese, and aluminum, along with chlorine, are moved.
