  • 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.

  • Hafnium Wikipedia

    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.

    Zirconium and hafnium separation at Y-12 . When then Captain Hyman G. Rickover completed his nuclear reactor training at the Clinton Laboratories in 1947, he quickly saw the advantage of using highly enriched uranium reactors in ships. That was when it was first realized that there was a need to separate hafnium from zirconium for pure zirconium.

  • Why is Hafnium Smaller Than Zirconium SAMaterials

    Zircon, SiO4, and baddeleyite ZrO2, are the most important sources of Hf and usually contain up to 2%. However, some Norwegian zircon minerals have been found to contain 20% Hf. Hafnium is predominantly lithophile in its behaviour, occurring in oxides and silicates as the Hf ion. Hafnium may be used as a pathfinder for Zr mineralisation.

  • Why Is Zirconium Used In Nuclear Reactors? | Refractory

    Initially, zirconium was not considered a suitable material for use in the nuclear industry, because studies have shown that zirconium’s effect on thermal neutron absorption can affect the efficiency of nuclear reactors. Later, researchers at the Oak Ridge Institute found that 2.5% of the hafnium in zirconium was responsible for its large thermal neutron capture cross-section.
