    Zirconium And Hafnium Statistics And Information

    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. The major end uses of zircon are refractories, foundry sands including investment casting, and ceramic opacification.

    Hafnium Periodic Table Of Elements Los Alamos National

    Hafnium is a ductile metal with a brilliant silver luster. Its properties are considerably influenced by presence of zirconium impurities. Of all the elements, zirconium and hafnium are two of the most difficult to separate. Although their chemistry is almost identical, the density of zirconium is about half of hafnium.

    Hafnium Oxide Zirconium Metal

    Pure zirconium oxide is a kind of advanced refractory raw material with a melting temperature of about 2900 . Zirconia usually contains a small amount of hafnium oxide, which is difficult to separate but has no obvious effect on the properties of zirconia. Zirconia has three crystalline forms monoclinic, tetragonal and cubic.

    Zirconium Alloys Characteristics And Uses

    Zirconium Alloys. Pure 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 and its alloys are widely used as a cladding ...

    Metallic Sponge Incendiary Compositions Teledyne

    The use of zirconium or hafnium metallic sponge allows the weight of the particles in the composition to be heavier, thus being capable of being projected a greater distance upon impact. The quality which allows the use of these particles is the increase in surface area of the sponge particles over the ordinary metallic particles.

    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 zirconiums 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.
