The commercial metal usually contains hafnium, but reactorgrade zirconium, for use in atomic work, is hafniumfree. Commercially pure zirconium is not a highstrength metal, with a tensile strength of about 220 MPa, elongation 40%, and Brinell hardness 30, or about the same physical properties as pure iron. But it is valued for atomicconstruction purposes because of its low neutroncapture cross section, .
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 .
Abstract: Zirconium tetrachloride containing hafnium tetrachloride is selectively reduced with liquid metallic tin to produce zirconium trichloride. The hafnium tetrachloride is then separated as a vapor from a slurry of zirconium trichloride and other solids, including stannous dichloride, in liquid metallic tin.

Metal–organic frameworks (MOFs) are highly versatile materials that find applications in several fields. Highly stable zirconium/hafniumbased MOFs were recently introduced and nowadays represent a rapidly growing family. Their unique and intriguing properties make them privileged materials and outstanding candidates in heterogeneous catalysis, finding use either as catalysts or catalyst ...
Hafnium and zirconium have nearly identical chemistry, which makes the two difficult to separate. About half of all hafnium metal manufactured is produced as a byproduct of zirconium refinement.
