Dysprosium Oxide is the main raw material for Dysprosium Metal which is widely used in Neodymium-Iron-Boron magnets, also has specialized uses in ceramics, glass, phosphors, lasers, and Dysprosium Metal halide lamps. High purity of Dysprosium Oxide is used in the electronics industry as an antireflection coating in photoelectric devices. 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.
