More info

Dysprosium (Dy) is a rare earth element with atomic number 66 and metallic silver luster. While it remains stable in air at room temperature, it can easily oxidize when exposed to oxygen and water at high temperatures, forming dysprosium oxide. Its properties are significantly impacted by the presence of trace impurities. HM stocks a wide variety of rare earth materials for use in electronics, petrochemicals, metallurgy, machinery, energy, environmental protection, agriculture, and other fields. We also offer pure metals and compounds for R&D applications.

Dysprosium (Dy) Metal Applications

  • 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.
