Dysprosium Metal Dy CAS 7429-91-6 For Additive Of NdFeB Magnets

Dysprosium, the element symbol Dy, is a silvery white rare earth metal, soft and has high ductility. It exhibits superconductivity near absolute zero, with melting and boiling points as high as 1412°C and 2562°C, respectively, and a density of 8.55g/cm³. Dysprosium is relatively stable in air, but reacts easily with air and water at high temperatures to form dysprosium oxide.
In the electronics industry, it is often used to manufacture components such as transistors, semiconductor tubes and integrated circuits to improve performance. In the aerospace industry, dysprosium is used to enhance electromagnetic compatibility and improve equipment safety due to its good electrical, thermal and corrosion resistance properties. In addition, dysprosium is a key element in the manufacture of high-performance permanent magnet materials and magnetostrictive alloys, which can significantly improve the coercivity and precision mobility of materials.

product details

Feature

Name: Dysprosium metal, distillation Dysprosium

Molecular formula: Dy

CAS: 7429-91-6

Molecular weight: 162.50

Description

Dysprosium can be made into various forms: Dysprosium Foil, Dysprosium block, Dysprosium sheet, Dysprosium powder, Dysprosium sputtering target. The abundance of Dysprosium in the earth's crust is 6 ppm, which is lower than that of Yttrium in heavy rare earth. It is a relatively rich heavy rare earth element, which provides a good resource base for its application. Dysprosium is a soft metal with glossy ductility. It is easy to be corroded by air at high temperature, but stable at room temperature. Work slowly with water.

Used

It is mainly used as an additive of NdFeB permanent magnet, the coercive force of the magnet can be increased by adding about 2-3% Dysprosium. Dysprosium is a necessary metal raw material for the preparation of TbDyFe (Terfenol) alloy, which can realize some precise mechanical movements. Dysprosium metal can also be used as magneto-optical storage material with high recording speed and reading sensitivity.
