Hafnium
(Hf) Metal |
|
 Hafnium
is a lustrous, silvery, ductile metal. It restists corrosion due to
formation of a tough, impenetrable oxide film on its surface. The metal is
unaffected by alkalis and acids, except hydrofluoric acid. Hafnium is
difficult to separate form zirconium, bacause the two elements have atoms
that are the same size.Hafnium and its alloys are used for control rods in
nuclear reactors and nuclear submarines because hafnium is excellent at
absorbing neutrons and it has a very high melting point and is corrosion
resistant. It is used in high-temperature alloys and ceramics, since some
of its compounds are very refractory: they will not melt except under the
most extreme temperatures.
