  • 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.Онлайн-запрос

  • Why Is Zirconium Used In Nuclear Reactors? | Refractory

    Sep 26, 2019· 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.Онлайн-запрос

  • Zirconium Atomic Radius Zr Periodic Table

    Zirconium is a lustrous, grey-white, strong transition metal that 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. Zirconium is widely used as a cladding for nuclear reactor fuels.Онлайн-запрос

  • Zirconium Element information, properties and uses

    Zirconium is used to make the cladding for uranium oxide fuel elements. As mined, zirconium contains 1-3% per cent of hafnium, which is chemically very similar, and although it is difficult to separate the two elements this has to be done for the metal used in the nuclear industry because hafnium absorbs neutrons very strongly.Онлайн-запрос

  • WebElements Periodic Table » Hafnium » the essentials

    Manganese; Meitnerium ☢ Most zirconium minerals contain 1 to 3% hafnium. Hafnium is a ductile metal with a brilliant silver lustre. Its properties are influenced considerably by the impurities of zirconium present. Of all the elements, zirconium and hafnium are two of the most difficult to separate. Hafnium is a Group 4 transition element.Онлайн-запрос

  • Pictures, stories, and facts about the element Hafnium in

    Hafnium and zirconium are quite difficult to separate, and even very pure zirconium is often sold with the understanding that there is several percent of hafnium contamination, and vice versa. Since they are chemically very similar (which is why they are hard to separate) this is often not a big deal, other than in nuclear applications.
