Multilingual: DysprosiumOxid, Oxyde De Dysprosium, Oxido Del Disprosio		 Dysprosium Oxide, is the main raw materials for Dysprosium Metal which is widely used in Neodymium-Iron-Boron magnets, also have specialized uses in ceramics, glass, phosphors, lasers and Dysprosium Metal halide lamp. High purity of Dysprosium Oxide is used in 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.
