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) Hafnium is not all that uncommon compared to many other exotic elements It occurs to the extent of 5 8 ppm of the Earth's upper crust by weight The reason why it took a long time to isolate is that its atoms have almost the identical size to those of zirconium along with which it typically occurs in minerals

Zirconium and hafnium

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 Hafnium and zirconium are quite difficult to separate and even very pure zirconium is often sold with the understanding that there is several percent of hafnium contamination and vice versa Since they are chemically very similar (which is why they are hard to separate) this is often not a big deal other than in nuclear applications

Separation of zirconium and hafnium Commercial zirconium metal typically contains 1–3% of hafnium which is usually not problematic because the chemical properties of hafnium and zirconium are very similar Their neutron-absorbing properties differ strongly however necessitating the separation of hafnium from zirconium for nuclear reactors Zirconium and hafnium alloys machine to an excellent finish and the operation requires relatively light horsepower compared with that for alloy steel Fine chips should not be allowed to accumulate on or near the machining equipment because they can be easily ignited

Zirconium Hafnium Manganese

  1. Zirconium alloy

    Commercial non-nuclear grade zirconium typically contains 1–5% of hafnium whose neutron absorption cross-section is 600x that of zirconium Hafnium must therefore be almost entirely removed (reduced to 0 02% of the alloy) for reactor applications

  2. Zirconium dioxide

    Zirconium dioxide (ZrO 2) sometimes known as zirconia (not to be confused with zircon) is a white crystalline oxide of zirconium Its most naturally occurring form with a monoclinic crystalline structure is the mineral baddeleyite
