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.
