[hide] *Discovery 1  ==Discovery[ Edit] == Erbium in 1843 is discovered by the chemist Carl Gustaf Mosander Swedish while investigating minerals. He called it to Ytterby, where it was first found. In1934 was pure metallic erbium erbium chloride with isolated by to reduce potassium vapor. ==Applications[ Edit] == Erbium is mostly used as photographic filter and the resilient property makes it a usable additive in alloys. Erbium is also widely used in photonics, because theband gap corresponds to the wavelength which has the highest fiber transmission. Other uses include:

In the glass industry is erbium oxide has a pink color, that, used for coloring glass. This glass is often used for sunglasses and cheap jewelry. ==Outstanding features[ Edit] == Erbium is a pretty soft and pliable metal with a bright metallic luster that at standard temperature and pressure is affected in the air more slowly than many other lanthanides. In visible light, ultraviolet and near infrared exhibits erbium a characteristic spectrum. Most of erbium salts have a pink color. ==Appearance<span class="mw-editsection" len="325" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:22.3999996185303px;color:rgb(37,37,37);font-family:sans-serif;">In nature as a free element, but not for erbium comes it occurs in several minerals in which also other lanthanides are found such as monaziet and consists principally of, bastnäsiet. The principal commercial sources of erbium are the minerals xenotiem and euxeniet. ==Isotopes<span class="mw-editsection" len="321" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:22.3999996185303px;color:rgb(37,37,37);font-family:sans-serif;">In nature come six stable isotopes for which There <sup len="3" style="line-height:1;">166 erbium about a third member. 23 radioactive isotopes are known, of which <sup len="3" style="line-height:1;">169 with a half-life of 9.4 days the most stable. ==Toxicology and safety<span class="mw-editsection" len="338" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:22.3999996185303px;color:rgb(37,37,37);font-family:sans-serif;">About the possibly harmful effects of erbium is still little known. It is to be expected that it's comparable to other lanthanides. Erbium in powder form is combustible.
 * Reinforcement fibers in fiber.
 * In nuclear installations, the neutron absorbing ability of erbium sure it as neutrons catcher can be used.
