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 into 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.

Application

  • Dysprosium is used, in conjunction with vanadium and other elements, in making laser materials and commercial lighting. Because of dysprosium's high thermal-neutron absorption cross-section, dysprosium-oxide–nickel cermets are used in neutron-absorbing control rods in nuclear reactors.
  • Dysprosium is used in dosimeters for measuring ionizing radiation.
  • Dysprosium iodide and dysprosium bromide are used in high-intensity metal-halide lamps. These compounds dissociate near the hot center of the lamp, releasing isolated dysprosium atoms. 
  • Several paramagnetic crystal salts of dysprosium (Dysprosium Gallium Garnet, DGG; Dysprosium Aluminum Garnet, DAG; Dysprosium Iron Garnet, DyIG) are used in adiabatic demagnetization refrigerators.

Packing: The products are vacuum-sealed. The MSDS and Material Certification Sheets will be packed with the product.
