What is Dysprosium?
'''Dysprosium''' ({{pronEng|dɪsˈproʊziəm}}) is a [[chemical element]] with the symbol '''Dy''' and [[atomic number]] 66. It has a very high melting temperature of 1,407°C. It can also absorb [[neutron]]s. This makes it very suitable for use with [[nuclear reactor]]s and [[laser]]s. Dysprosium is a [[rare earth element]] that has a metallic, bright silver luster. Dysprosium was first identified in [[Paris]] in 1886 by French chemist [[Paul Émile Lecoq de Boisbaudran]]. == Compounds == * [[Fluoride]]s: [[dysprosium(III) fluoride|DyF<sub>3</sub>]] * [[Chloride]]s: [[dysprosium(II) chloride|DyCl<sub>2</sub>]], [[dysprosium(III) chloride|DyCl<sub>3</sub>]] * [[Bromide]]s: [[dysprosium(II) bromide|DyBr<sub>2</sub>]], [[dysprosium(III) bromide|DyBr<sub>3</sub>]] * [[Iodide]]s: [[dysprosium(II) iodide|DyI<sub>2</sub>]], [[dysprosium(III) iodide|DyI<sub>3</sub>]] * [[Oxide]]s: [[dysprosium(III) oxide|Dy<sub>2</sub>O<sub>3</sub>]] * [[Sulfide]]s: [[dysprosium(III) sulfide|Dy<sub>2</sub>S<sub>3</sub>]] * [[Nitride]]s: [[dysprosium(III) nitride|DyN]] == Other websites == {{Commons|Dysprosium}} {{wiktionary|dysprosium}} * [http://www.webelements.com/webelements/elements/text/Dy/key.html WebElements.com – Dysprosium] * [http://periodic.lanl.gov/elements/66.html Los Alamos National Laboratory – Dysprosium] {{Webarchive|url=https://web.archive.org/web/20090313003257/http://periodic.lanl.gov/elements/66.html |date=2009-03-13 }} {{chem-stub}} {{Periodic Table}} [[Category:Lanthanides]]
