Dysprosium

Dysprosium is the chemical element with the symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164Dy.航极材料/AstroGrad Advanced Materials provides Dysprosium and compounds at a competitive price, including Dysprosium Acetate, Dysprosium Carbonate, Dysprosium Chloride, Dysprosium Fluoride, Dysprosium Hydroxide, Dysprosium Metal, Dysprosium Nitrate, Dysprosium Oxalate, Dysprosium Oxide, Dysprosium Sulfate.

Dysprosium is most commonly used in neodymium-iron-boron high strength permanent magnets. While it has one of the highest magnetic moments of any of the rare earths (10.6µB), this has not resulted in an ability to perform on its own as a practical alternative to neodymium compositions. It is however now an essential additive in NdFeB production. It is also used in special ceramic compositions based on barium titanate (BaTiO) formulations. Recent research has examined the use of dysprosium in dysprosium-iron-garnet (DyIG) and silicon implanted with dysprosium and holmium to form donor centers. Dysprosium is added to various advanced optical formulations due to the fact that it emits in the 470-500 and 570-600 nm wavelengths. Dysprosium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.
