State at 20 °C Solid Discovery Discovered By: Carl Mosander It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden, from which it got its name. Period Number: 6. Otherwise it looks much like the other rare earths. [8], Erbium (for Ytterby, a village in Sweden) was discovered by Carl Gustaf Mosander in 1843. Phase at Room Temperature: Solid. Erbium sesquioxide (oxide containing three atoms of oxygen and two atoms of another element) are called erbia. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife.The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Erbium is a chemical radioactive element present as the eleventh element in the lanthanide series of the periodic table. Need an editable periodic table to edit? The number of erbium-related luminescence transitions decreases dramatically to eight sharp transitions when the MBE growth temperature is decreased from 600°C to 580 o C. [128] The photoluminescence efficiency of erbium-doped AlGaAs is an order of magnitude stronger than that of erbium … Erbia has a pink color and is used to color glass and glazes. Atomic Number of Erbium is 68.. Chemical symbol for Erbium is Er. Its salts are rose-colored, and the element has characteristic sharp absorption spectra bands in visible light, ultraviolet, and near infrared. Fairly pure Er2O3 was independently isolated in 1905 by Georges Urbain and Charles James. Benjamin Brenny (2017, TNO) Erbium definition is - a metallic chemical element of the rare-earth group with atomic number 68 that is used especially in lasers, infrared light filters, and optical fibers. Mosander was not certain of the purity of the oxides and later tests confirmed his uncertainty. Erbium-doped glasses or crystals can be used as optical amplification media, where Er3+ ions are optically pumped at around 980 or 1480 nm and then radiate light at 1530 nm in stimulated emission.

Below is a list of Creative Erbium slogans for chemistry assignments, science projects & project presentations. Crushed minerals are attacked by hydrochloric or sulfuric acid that transforms insoluble rare-earth oxides into soluble chlorides or sulfates. This color behavior is similar to what Mosander and the other early workers in the lanthanides would have seen in their extracts from the gadolinite minerals of Ytterby. Named after Ytterby, a village in Sweden. Registered agent is Laura Semerjian, 34319 Lamborn St Temecula CA 92592. [21] The same fibers can be used to create fiber lasers. [22] An erbium-nickel alloy Er3Ni has an unusually high specific heat capacity at liquid-helium temperatures and is used in cryocoolers; a mixture of 65% Er3Co and 35% Er0.9Yb0.1Ni by volume improves the specific heat capacity even more.

The principal commercial sources of erbium are from the minerals xenotime and euxenite, and most recently, the ion adsorption clays of southern China; in consequence, China has now become the principal global supplier of this element. Erbium was discovered by Carl Gustaf Mosander in 1842. Erbium does not play any known biological role, but is thought to be able to stimulate metabolism. When the concentrate is dissolved in acid, the erbia liberates enough erbium ion to impart a distinct and characteristic pink color to the solution. Erbium is an element with atomic symbol Er, atomic number 68, and atomic weight 167.259. A spectroscopist mistakenly switched the names of the two elements during spectroscopy. Company is incorporated on 23rd December 2016. [16] It was only in the 1990s that the price for Chinese-derived erbium oxide became low enough for erbium to be considered for use as a colorant in art glass.[17].

Erbium Group is an entity registered at California with company number C3971246. Erbium Limited has 2 shareholders. NCI Thesaurus (NCIt) Erbium is a lanthanoid atom and a f-block element atom. [4], When added to vanadium as an alloy, erbium lowers hardness and improves workability. Hesketh, in Encyclopedia of Materials: Science and Technology, 2002. Such shallow tissue deposition of laser energy is helpful in laser surgery, and for the efficient production of steam which produces enamel ablation by common types of dental laser. The company has 7 directors who have also been the directors of 45 other Irish companies between them; 10 of which are now closed. Naturally, occurring Erbium is found in chemical combination with other naturally occurring elements. The rare earth ions are then selectively washed out by suitable complexing agent. Erbium also has some uses in the nuclear power industry. The oxalates are converted to oxides by annealing. Name Origin Named after the Swedish town, Ytterby. occurs with yttrium. Erbium can also be used in erbium-doped waveguide amplifiers. These dopants help prevent clustering of Er ions and transfer the energy more efficiently between excitation light (also known as optical pump) and the signal. [4] Metallic erbium in dust form presents a fire and explosion hazard. Atomic Number: 68. In this process, rare-earth ions are sorbed onto suitable ion-exchange resin by exchange with hydrogen, ammonium or cupric ions present in the resin.

[citation needed], Erbium-doped optical silica-glass fibers are the active element in erbium-doped fiber amplifiers (EDFAs), which are widely used in optical communications. [10]:701[11][12][13][14][15], Erbia and terbia, however, were confused at this time. A trivalent element, pure erbium metal is malleable (or easily shaped), soft yet stable in air, and does not oxidize as quickly as some other rare-earth metals. In order to work efficiently, erbium-doped fiber is usually co-doped with glass modifiers/homogenizers, often aluminum or phosphorus. Terbium is a chemical element with the symbol Tb and atomic number 65. The oxides are dissolved in nitric acid that excludes one of the main components, cerium, whose oxide is insoluble in HNO3. Although erbium (along with several rare earths) was discovered in the mid-19th century, it was not isolated as a pure element until 1935 because the group of elements had such similar properties. A large variety of medical applications (i.e. Sigma-Aldrich offers a number of Erbium products. It is widely used in the form of the trivalent ion Er 3+ as the laser-active dopant of gain media based on various host materials, including both crystals and glasses . Its sesquioxide is called erbia. Number of protons in Erbium is 68. The 1550 nm wavelength is especially important for optical communications because standard single mode optical fibers have minimal loss at this particular wavelength. Search for "Gelson Luz" in your favorite browser to learn more. Erbium's principal uses involve its pink-colored Er3+ ions, which have optical fluorescent properties particularly useful in certain laser applications. Like other rare earths, this element is never found as a free element in nature but is found bound in monazite sand ores. 10XX,52,11XX,17,12XX,7,13XX,4,15XX,16,3XXX,2,40XX,10,41XX,12,43XX,5,44XX,4,46XX,5,47XX,3,48XX,3,5XXX,23,6XXX,3,71XX,1,8XXX,22,92XX,5,93XX,1,94XX,4,98XX,2,ASTM,171,Atomic-Mass,327,Atomic-Number,436,Atomic-Radius,86,Atomic-Symbol,329,Atomic-Volume,94,Boiling-Point,94,CBS,6,Chemical-Elements,100,Chemical-Symbol,217,CMDS,13,Coefficient-of-Thermal-Expansion,85,Covalent-Radius,87,Crystal-Structure,109,CS,17,CVS,3,Density,309,Elastic-Modulus,30,Electrical-Conductivity,79,Electro-Affinity,87,Electron-Configuration,109,Electronegativity,102,Electrons-per-Shell,112,Enthalpy-of-Fusion,93,Enthalpy-of-Vaporization,95,Group-Number,218,HCS,14,Heat-of-Fusion,87,Heat-of-Vaporization,85,HMCS,16,Ionic-Radius,78,Ionization-Energy,102,Ionization-Potential,101,LCS,21,List,201,MCS,17,MDS,14,Melting-Point,96,MS,4,NCMDBS,6,NCMDS,31,NCS,2,NMDS,8,Oxidation-States,104,Period-Number,107,Properties,40,RCLS,1,RCS,16,RRCLS,3,RRCS,4,SAE,201,Site,2,SMS,5,Specific-Gravity,83,Specific-Heat,92,Specific-Weight,1,Tests,2,Thermal-Conductivity,105,Valence-Electrons,98.

Its compounds like Erbium … When it is artificially isolated its appearance is a silvery-white solid metal. After 1860, terbia was renamed erbia and after 1877 what had been known as erbia was renamed terbia. Reasonably pure erbium metal was not produced until 1934 when Wilhelm Klemm and Heinrich Bommer reduced the anhydrous chloride with potassium vapor. This process results in an unusually mechanically simple laser optical amplifier for signals transmitted by fiber optics.
