  • Hafnium - Element information, properties and uses 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.

  • Hafnium | chemical element | BritannicaHafnium is chemically similar to zirconium. Both transition metals have similar electronic configurations, and their ionic radii (Zr 4+, 0.74 Å, and Hf 4+, 0.75 Å) and atomic radii (zirconium, 1.45 Å, and hafnium, 1.44 Å) are nearly identical because of the influence of the lanthanoid contraction. In fact, the chemical behaviour of these
