Dysprosium brand chemical composition
general characteristics
Dysprosium — lanthanide rare earth element group, atomic number 66, chemical symbol Dy. It is a bright silvery luster metal. The content in the lithosphere 5x10 -4%. It occurs as an incidental element in the form of salts, along with other rare earth metals in a variety of minerals. Bastenzita apatite, gadolinite, monazite, etc. The history of the discovery… In 1886 during the spectroscopic analysis of holmium land a new element has been found that in a pure form was able to identify in 1906 Zh.Urben. modern industry gets dysprosium recovery DyCl 3 or 3 DyF lithium, calcium or sodium. Like other non-ferrous metals, it is supplied to a circle, plate, wire.
Physicochemical characteristics
To + 1384 ° C dysprosium has a hexagonal α-lattice, and at a higher temperature — β-cubic lattice. In the air t ° up to 100 ° C it oxidizes slowly. But when heated actively reacts with O 2, H 2, N 2, halogen. He quickly dissolved mineral acids, alkalis but Mr him almost no effect.
| The atomic number of Eu | The atomic (molar) mass g / mol | The degree of oxidation | Density [g / cm3] | Melting point t ° C | The boiling point of t ° C | The heat of fusion kJ / kg |
|---|---|---|---|---|---|---|
| number 66 | 162.5 | 3 | 8.56 | 1413 ° C | 2562 ° C | 291 |
application
Dysprosium gives the zinc alloys increased wear resistance. As part of zirconium expands the width of thermal neutron capture and improves workability of the alloy. In medical lasers dysprosium ions excite infrared length of 2.36 m. it is relevant as an effective catalyst in industrial chemistry. Borate, boride, gafnata, dysprosium oxide actively captures neutrons. These compounds are part of protective paints, enamels, used in nuclear power, and the control rods and fuel elements. Iron doped dysprosium — a powerful magnetostrictive material. GOST 23 862.3−79 normalizes the content of impurities of dysprosium oxide, determined by spectral analysis.
