Dysprosium Oxide Properties:

Dysprosium Oxide (Dy2O3) is a sesquioxide compound of the rare earth metal dysprosium. It is a pastel yellowish-greenish, slightly hygroscopic powder. Insoluble in water, soluble in acid and ethanol. The product has high purity, small particle size, uniform distribution, specific surface area, high surface activity, low apparent density.

Dysprosium Oxide Applications:

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 cermet is 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.
