Zirconium and Hafnium Statistics and Information

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.

OverviewCharacteristicsProductionCompoundsHistoryApplicationsSafetySee also

Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Z

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered. Hafnium is named after Hafnia, the Latin name for Copenhagen, where it was discovered.

Group 4 element - Wikipedia

Zirconium has a very low and hafnium has a high thermal neutron-capture cross-section. Therefore, zirconium (mostly as zircaloy) is used as cladding of fuel rods in nuclear reactors, while hafnium is used in control rods for nuclear reactors, because each hafnium atom can absorb multiple neutrons.

Zirconium and hafnium - USGS

Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials.

Zirconium alloy - Wikipedia

Production and properties. Commercial non-nuclear grade zirconium typically contains 15% of hafnium, whose neutron absorption cross-section is 600x that of zirconium.Hafnium must therefore be almost entirely removed (reduced to < 0.02% of the alloy) for reactor applications.

The principal source of zirconium and hafnium is zircon, though a minor source is baddeleyite, mined only in Brazil.

The principal sources of zircon are therefore alluvial deposits, which are mined in many countries of five continents.
