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 Zirkonium (chemická značka Zr, latinsky zirconium) je šedý až stříbřitě bílý, kovový prvek, mimořádně odolný proti korozi. Hlavní uplatnění nalézá v jaderné energetice, protože vykazuje velmi nízký účinný průřez pro záchyt neutronů.Dále je složkou různých slitin a protikorozních ochranných vrstev Zirconium-88. 88 Zr is a radioisotope of zirconium with a half-life of 83.4 days.

Zirconium has five stable isotopes, of which a few are used for the production of radioisotopes. Although radioactive Zr-95 is a fission product, it can also produced by neutron irradiation of Zr-94. Zr-96 has been used for the production of the radioisotope Zr-97. Zr-90 can be used for the production of the PET isotope Nb-90 However, the radioactive isotopes zirconium 95 is a radionuclide with considerably high half-life and continue to persist in the environment and cause cancer risks for decades . Isotopes of Zirconium. Zirconium have five natural isotopes, zirconium-90 (51.46 percent), zirconium-92 (17.11 percent), zirconium-91 (11.23 percent), zirconium-96. Radioactive zirconium (Zr) isotopes are produced in large quantities in nuclear fission reactors; one of the most common fragments in uranium fission is the radioactive 95 Zr. For example, the estimated released 95 Zr activity of the Fukushima and Chernobyl accidents is considered to have detrimental health effects not only via irradiation, but also via the intake of edibles[1, 2]

Get yourself tested here. Most people have never heard of zirconium but this toxic heavy metal is used in society everyday and its not uncommon to find some degree of zirconium toxicity in people. Zirconium is toxic to humans and it is also radioactive, it is considered an irritant at low levels and higher levels are considered immediately dangerous to life and. Zirconium 705 is alloyed with Niobium to increase its strength and improve its formability. Zirconium is a reactive metal that has a high affinity for oxygen resulting in the formation of a protective oxide layer in air at room temperature. This protective oxide gives Zirconium alloys their superior corrosion resistance Dichlorobis(1-neomenthylindenyl)-zirconium 95% Synonym: Dichlorobis[(1,2,3,3a,7a-η)-1-[(1S,2S,5R)-5-methyl-2-(1-methylethyl)cyclohexyl]-1H-inden-1-yl]-zirconium, ZACA catalyst CAS Number 148347-88-.

Zirconium is used in nuclear reactors to provide the cladding, or outer covering, for the cylindrical fuel rods that power a nuclear reaction. Packed inside the zirconium cladding are pellets of. Zr - Zirconium Introduction Zirconium belongs to group 4 of the periodic table, which also includes Ti and Hf. The element has an atomic number of 40, an atomic mass of 91, one main oxidation state (+4) and five naturally occurring isotopes (90Zr, 91Zr, 92Zr, 94Zr and 96Zr), of which 90Zr is the most abundant at 51.5% of the total mass Zirconium is a grayish-white metal, lustrous, and quite corrosion-resistant. Zirconium is lighter than steel and its hardness is similar to copper. When it is finely divided into a powder, zirconium can spontaneously ignite in air, especially at high temperatures. (It is much more difficult to ignite the solid metal. 13765-95-2 - LEHFSLREWWMLPU-UHFFFAOYSA-B - Zirconium phosphate - Similar structures search, synonyms, formulas, resource links, and other chemical information .
