dys·pro·si·um

 (dĭs-prō′zē-əm, -zhē-əm)
n. Symbol Dy
A soft, silvery metallic element of the lanthanide series occurring in the minerals monazite and bastnaesite, used in nuclear reactor control rods and in the manufacture of laser materials and compact discs. Atomic number 66; atomic weight 162.50; melting point 1,412°C; boiling point 2,567°C; specific gravity 8.551; valence 3. See Periodic Table.

[New Latin, from Greek dusprositos, difficult to approach (from its rarity in nature) : dus-, dys- + prositos, approachable (from prosienai, to approach : pros-, toward + ienai, i-, to go; see ei- in Indo-European roots).]

dysprosium

(dɪsˈprəʊsɪəm)
n
(Elements & Compounds) a soft silvery-white metallic element of the lanthanide series: used in laser materials and as a neutron absorber in nuclear control rods. Symbol: Dy; atomic no: 66; atomic wt: 162.50; valency: 3; relative density: 8.551; melting pt: 1412°C; boiling pt: 2567°C
[C20: New Latin, from Greek dusprositos difficult to get near + -ium]

dys•pro•si•um

(dɪsˈproʊ si əm, -ʃi-)

n.
a rare-earth element that is highly reactive and paramagnetic and used to absorb neutrons in nuclear reactors. Symbol: Dy; at. wt.: 162.50; at. no.: 66.
[< French (1886)]

dys·pro·si·um

(dĭs-prō′zē-əm)
Symbol Dy A soft, silvery metallic element of the lanthanide series. Because it has a high melting point and absorbs neutrons well, dysprosium is used to help control nuclear reactions. Atomic number 66. See Periodic Table.

The Licensor created the MSX Technology specifically for the recovery of Neodymium, Dysprosium and Praseodymium on a mandate from the U.
Using the two isotopes of dysprosium as "clocks," they also showed that as the Earth moved closer to or farther from the sun over the course of two years, the relative frequency of these "clocks" remained constant, as Einstein predicted in his general theory of relativity.
Japan plans to import 30 tonnes of dysprosium from Kazakhstan this year, the daily said, adding that it plans to raise the shipment next year to more than 50 tonnes accounting for 10 percent of Japan s annual demand for the mineral.
Rare earth metals like neodymium and dysprosium are used in the powerful magnets in motors that power hybrid and electric cars, and demand is expected to surge as more of the environmentally friendly cars hit the market.
Demand for the magnets, made of such rare earths as neodymium and dysprosium, is expected to grow due to rising sales of hybrid and other eco-friendly cars.
If they ever live up to their promise, nanocomposite magnets should reduce the demand for both neodymium and for another rare earth element called dysprosium.
The rare earth sector covers companies with operations involving exploration, extraction, transport, processing or any other business involving any of the following 17 rare earth elements: Scandium, Yttrium, Lanthanum, Lutetium, Ytterbium, Thulium, Erbium, Holmium, Dysprosium, Terbium, Gadolinium, Europium, Samarium, Promethium, Neodymium, Praseodymium, and Cerium.
This strategy aims to overcome the 'rare-element crisis'that was triggered by increasing demand for such elements as lithium, used in batteries, and dysprosium for Ne-Fe-B permanent magnets.
And some of these magnets also contain 3 to 10 percent of dysprosium, which allows the magnets to reach higher temperatures and still maintain their strength.
dysprosium, which are used for making LCD panels and hybrid vehicles, the
Among a variety of rare-earth elements, neodymium and dysprosium are widely used as a magnetic material for motors in environmentally friendly vehicles and home appliances, while erbium is used as a dopant in optical fibers and cerium as an abrasive for polishing liquid crystal display (LCD) glass.
1) There was already ample Western concern about potential diminishing access to supplies of REEs, particularly after a 2009 draft report written by China's Ministry of Industry and Information Technology called for a total ban on foreign shipments of terbium, dysprosium, ytterbium, thulium, and lutetium, and a restriction of neodymium, europium, cerium, and lanthanum exports.
