Zirconium – Refractory Metal
Zirconium is obtained from zircon sand, which also contains a small percentage of hafnium oxide. In making reactorgrade zirconium, the hafnium must be removed so that the concentration of hafnium in the zirconium will be no more than 0. 01 per cent. The production of hafnium is largely dependent on the production of reactorgrade zirconium.

Zirconium | Teach Nuclear
Commercialgrade zirconium contains from 1 to 3% hafnium. Zirconium has a low absorption cross section for neutrons, and is therefore used for nuclear energy applications, such as for cladding fuel elements. Commercial nuclear power generation now takes more than 90% of zirconium metal production.
