Hafnium is a lustrous, silvery metal that is also extremely ductile. Hafnium is extremely resistant to corrosion, as when it is exposed to air, hafnium produces a tough, impenetrable oxide layer on its surface.
APPLICATIONS IN METALLURGY
The main use for Hafnium is in Nuclear industry and Hafnium is classed as a ‘dual use’ metal under the ‘Non-Proliferation of Nuclear Weapons Treaty’. Import/export licences and end user statements will be required in a number of instances.
The largest non-nuclear use of Hafnium is in high temperature Nickel base single crystal alloys for aero and industrial gas turbine blades, followed by used in plasma-cutting equipment and processors, where temperature resistance is a factor. Hafnium oxide is used in blue lasers for DVD readers, and also in CVD/PVD for thin films.
