While a number of ore types, including monazite and bastnasite, may contain dysprosium, the sources with the highest percentage of contained dysprosium are the ion adsorption clays of Jiangxi Province, China and xenotime ores in South China and Malaysia. The metal costs about $300/kg in purities of 99+%. Like other rare-earth or lanthanide elements, dysprosium occurs … Dysprosium fluoride can be reduced into metal ingots by heating with calcium at high temperatures in tantalum crucibles. The metal has been prepared by metallothermic reduction of the anhydrous halides with alkali or alkaline-earth metals. While relatively stable in air at ambient temperatures, dysprosium metal will react with cold water and rapidly dissolves in contact with acids. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps. Dysprosium's physical characteristics can be greatly affected by even small amounts of impurities. The metal is soft enough to be cut with a knife and can be machined without sparking if overheating is avoided. Erbium oxide, itself, was found to be harboring two other elements, holmium, and thulium. Global production of dysprosium is limited to about 1800 metric tonnes (contained dysprosium) annually. Dysprosium Oxide (Dy 2 O 3) is a sesquioxide compound of the rare earth metal dysprosium. Dysprosium is added to various advanced optical formulations due to the fact that it emits in the 470-500 and 570-600 nm wavelengths and is an essential additive in NdFeB magnets. 66, symbol Dy, weight at 162.50, is most commonly used as in neodymium-iron-boron high strength permanent magnets It is really just a nonmetal. It also occurs in the products of nuclear fission. Let us know if you have suggestions to improve this article (requires login). NdFeB magnets are now the standard in electronic applications and hybrid electric vehicles. This amounts to only 30 cents per gram! Dysprosium metal 99.5% . Argus price assessments cover the most active trading regions for each commodity. The metal slowly reacts with water and quickly dissolves in diluted acids—except hydrofluoric acid (HF), in which it forms a protective layer of insoluble DyF3. The metal is a very strong paramagnet above approximately 180 K (−93 °C, or −136 °F); it is antiferromagnetic between about 90 (−183 °C, or −298 °F) and 180 K and ferromagnetic below 90 K. French chemist Paul-Émile Lecoq de Boisbaudran first found this element (1886) associated with holmium and other heavy lanthanides; French chemist Georges Urbain later (1906) was able to prepare a reasonably pure fraction.

This accounts for only about 1 percent of all rare earth refined each year. Chemically, dysprosium behaves as a typical trivalent rare earth and forms a series of pale yellow compounds in which its oxidation state is +3. Stanford Advanced Materials supplies high-purity dysprosium metal and dysprosium metal powder. The Ames Laboratory, along with the Naval Ordnance Laboratory, was also central in developing one of the first major uses for dysprosium, Terfenol-D. Dysprosium metal belongs to the Lanthanides metals, also called rare-earth metals. Like the other metals in the rare earths group, dysprosium is usually separated from its kin via time consuming processes that drive up the cost of getting the isolated element. Dysprosium metal shiny sample of 1 gram 99,95% in glass vial In hydrofluoric acid, however, the heavy rare earth metal will form a protective layer of dysprosium fluoride (DyF3). The French chemist Paul-Emile Lecoq de Boisbadran first recognized dysprosium as an independent element in 1886 while he was analyzing erbium oxide. Like other rare earth elements, it has many applications in modern society. Along with holmium, dysprosium also has the highest magnetic moment (the strength and direction of pull resulting affected by a magnetic field) of any element. This work using the ASM metallisation process has confirmed ASM’s ability to produce the key permanent magnet metals (dysprosium, praseodymium and neodymium) and alloys that will be sourced from its Dubbo Project in central west NSW. Carbon is a nonmetal but can sometimes be classified as a metalloid. Dysprosium (Dy), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Research by General Motors and Sumitomo Special Metals led to the creation of these stronger, cheaper versions of the first permanent (samarium-cobalt) magnets, which had been developed 20 years earlier. The naturally occurring isotopes are all stable and have mass numbers 164 (natural abundance 28.3 percent), 162 (25.5 percent), 163 (24.9 percent), 161 (18.9 percent), 160 (2.33 percent), 158 (0.10 percent), and 156 (0.06 percent). Click here to read more about dysprosium applications. Like the other metals in the rare earths group, dysprosium is usually separated from its kin via time consuming processes that drive up the cost of getting the isolated element.

China dysprosium metal - find detail silver element found from nikyc peace m The major use of dysprosium is as an alloying addition to Nd2Fe14B permanent magnet materials (in which some of the neodymium is substituted with dysprosium) to increase both the Curie point and especially the coercivity and, therefore, improve the high-temperature performance of the alloy. Our editors will review what you’ve submitted and determine whether to revise the article. Boisbaudran developed an intricate and time-consuming procedure for the separation of dysprosium. There are 7 isotopes of dysprosium in nature: 156 Dy, 158 Dy, 160 Dy, 161 Dy, 162 Dy, 163 Dy and 164 Dy. The cost of dysprosium metal has dropped in recent years since the development of ion-exchange and solvent extraction techniques, and the discovery of large ore bodies. It is the best material for capturing hot neutrons, which has some applications in controlling nuclear processes. Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.
