Dysprosium Oxide 99.99% is the main raw materials for Dysprosium Metal which is widely used in Neodymium-Iron-Boron magnets, also have specialized uses in phosphors. 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 and its compounds are highly susceptible to magnetization, they are employed in various data-storage applications, such as in hard disks. High purity of Dysprosium Oxide is used in electronics industry as an antireflection coating in photoelectric devices.
