Facts, pictures, stories about the element Hafnium in the ...
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.Get Price

Hafnium is not all that uncommon compared to many other exotic elements. It occurs to the extent of 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.Get Price

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;zargun, "goldlike" or "as gold")), the most important source of zirconium. It is a lustrous, greywhite, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.Get Price

Zirconium and hafnium are corrosionresistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO 4, or as zirconium oxide or other zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials.Get Price
Hafnium is a shiny and silvery metal exhibiting ductile features. It is usually resistant to corrosion and exhibits similar chemical properties to that of zirconium. This similarity is because of the presence of valence electrons which are same and that of the same group. The impurities present in the zirconium highly affects the hafnium metal.Get Price
