Hafnium (Hf)

Hafnium is a lustrous, silvery, ductile metal. It resists corrosion due to formation of a tough impenetrable oxide film on its surface. hafnium chemically resembles zirconium and is found in zirconium minerals.


Hafnium has a good thermal absorption so is used in control rods in nuclear reactors and nuclear submarines. It has been successfully alloyed with several metals including iron, titanium and niobium.
