It was observed that separation of zirconium and hafnium is favored by high acidities, but considering that this is a very drastic condition, it is necessary to evaluate in what way the acidity influences the Zr/Hf separation, in other to better understand the system and to seek a way to decrease the acidity of the process. According to the results presented above, we chose to continue these ...

· Hafnium does not exist freely in nature and is found to be always associated with zirconium ores such as Zircon sand (ZrSiO 4) or Baddeleyite (ZrO 2) . Zirconium ores contain up to 1–2% hafnium. Zirconium has very less neutron absorption crosssection and therefore it is used as cladding for nuclear fuel and as various structural components in the nuclear reactor cores, as such Zr .

Zirconium and hafnium

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 (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.
