Dysprosium

Dysprosium is a silvery-white, lustrous rare earth metal that is solid at room temperature, with a melting point of 1412 °C and a boiling point of 2567 °C; it is relatively soft, malleable, and exhibits low volatility under standard conditions. It is classified as a lanthanide element and a heavy rare earth metal. Dysprosium is primarily used as an alloying additive—especially in neodymium–iron–boron (NdFeB) permanent magnets—to enhance coercivity and thermal stability. Its main application areas include high-performance motors and generators for electric vehicles and wind turbines, as well as in nuclear reactor control rods due to its high neutron absorption cross-section.

Dysprosium is most commonly used as in Neodymium-iron-boron high strength permanent magnets. While it has one of the highest magnetic moments of any of the rare earths (10.6uB), 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 BaTiO formulations.Dysprosium is used, in conjunction with Vanadium and other elements, in making laser materials and commercial lighting. Nanofibers of Dysprosium compounds have high strength and large surface area. Therefore, they can be used to reinforce other materials and as a catalyst.Recent research has examined the use of Dysprosium in Dysprosium-iron-garnet (DyFeG) and silicon implanted with Dysprosium and Holmium to form donor centers.Dysprosium Metal is an important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of high purity Dysprosium Metal is in the magnetostrictive alloy TEFENOL-D. There are also other applications for some special master alloys. Dysprosium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder. It is highly susceptible to magnetization, they are employed in various data-storage applications, such as in hard disks.
