Sep 29, 2017 · Mendeleev predicted Hafnium's existence when he developed the periodic table in 1869, but didn't live to see any, because pure Hafnium (symbol Hf) doesn't occur in nature; it's always bound with Zirconium (Zr) compounds – usually in a Hf:Zr ratio of 1:50 – and it's hard to extract. Until recently, Hafnium was just a low value by .

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, ionic radii, and ionic potentials.
