Hafnium is a adaptable metal with a ablaze argent lustre. Its backdrop are afflicted appreciably by the algae of zirconium present. Of all the elements, zirconium and hafnium are two of the a lot of difficult to separate. Hafnium is a Group 4 alteration element.
Because hafnium has a acceptable assimilation cantankerous area for thermal neutrons (almost 600 times that of zirconium), has accomplished automated properties, and is acutely bane resistant, it is acclimated for nuclear reactor ascendancy rods.
Hafnium carbide is the a lot of adverse bifold agreement known, and the nitride is the a lot of adverse metal nitride (m.p. 3310°C).
Hafnium is a acceptable cushion of neutrons and is acclimated in the ascendancy rods of nuclear reactors. Hafnium is aswell acclimated in exhaustion tubes as a getter, a actual that combines with and removes trace gases from exhaustion tubes. Hafnium has been acclimated as an alloying abettor in iron, titanium, niobium and added metals.
