New product rare earth metal block Erbium pure 99.5%

Erbiumis achemical elementwith symbolErandatomic number68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. It is alanthanide, arare earth element, originally found in thegadolinitemine inYtterbyinSweden, from which it got its name.Chemical Component %:Pictures:
Applications:
Erbium's everyday uses are varied. It is commonly used as aphotographic filter, and because of its resilience it is useful as a metallurgical additive. Other uses:

Used innucleartechnology in neutron-absorbingcontrol rods.[3][13]When added tovanadiumas analloy, erbium lowers hardness and improves workability.[14]Erbium oxidehas a pink color, and is sometimes used as a colorant forglass,cubic zirconiaandporcelain. The glass is then often used insunglassesand cheMining Machinery apjewelry.[14]Erbium-dopedoptical silica-glass fibersare the active element inerbium-doped fiber amplifiers(EDFAs), which are wiBall Screw dely used inoptical communications.[15]The same fibers can be used to create fOther Manufacturing & Processing Machinery iberlasers. In order to Detector work efficiently, erbium-doped fiber is usually co-doped with glass modifiers/homogenizers, often aCrane luminum or phosphorus. These dopants help prevent clustering of Er-ions and transfer the energy more efficiently between the Er ions and the signal. Co-doping of optical fiber with Er and Yb is used inhigh-power Er/Yb fiber lasers. Erbium can also be used inerbium-doped waveguide amplifiers.[3]An erbium-nickelalloy Er3Ni has an unusually high specific heat capacity at liquid-helium temperatures and is used incryocoolers; a mixture of 65% Er3Coand 35% Er0.9Yb0.1Ni by volume improves the specific heat capacity even more.A large variety of medical applications (i.e. dermatology, dentistry) utilize erbium ion's2940nmemission (seeEr:YAG laser), which is highly absorbed in water (absorption coefficientabout12000/cm). Such shallow tissue deposition of laser energy is necessary for laser surgery, and the efficient production of steam for laser enamel ablation in dentistry.
