Hafnium (Hf)

Hafnium is always found in minor quantities in Zirconium minerals. Hafnium is a silvery shining metal and very easy to deform as a pure element. The main field of application is the nuclear technology. Due to the high neutron capture cross section Hafnium is used in control-rods for regulation of chain reaction in nuclear reactors.

Significant Characteristics and Applications:

• high corrosion resistance
• high neutron capture cross section
• getter-effect on oxygen and nitrogen

Used as control-rods for nuclear technology, components for lighting technology, alloying element of superalloys, wear-resistant coating and optical coating.

ASTM Standard Specifications:
ASTM B737 (Hot Rolled and/or Cold Finished Hafnium Rod and Wire)
