Dysprosium Oxide is a highly insoluble thermally stable Dysprosium source suitable for glass, optic and ceramic applications. Dysprosium oxide is a white powder that reacts with acids to produce dysprosium salts. Dysprosium Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Dysprosium is added to various advanced optical formulations due to the fact that it emits in the 470-500 and 570-600 nm wavelengths and is an essential additive in NdFeB magnets. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systemsHigh Purity (99.999%) Dysprosium Oxide (Dy2O3) Powder. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stablemaking them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Dysprosium oxide is also available in pellets, pieces, powder, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). Additional technical, research and safety (SDS) information is available.

It is used as a raw material for the preparation of dysprosium, as an additive for glass, NdFeB permanent magnets, and also in metal halide lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and in the atomic energy industry. Dysprosium oxide can also be used as an additive for NdFeB permanent magnets. Adding about 2~3% dysprosium to this magnet can improve its coercivity. In the past, the demand for dysprosium was not large, but with the development of NdFeB magnets With the increase in demand for magnets, it has become a necessary additive element, and the grade must be around 95 to 99.9%, and the demand is also increasing rapidly. Dysprosium oxide is also used as a raw material for the preparation of dysprosium metal, as an additive for glass, NdFeB permanent magnets, and in metal halide lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and in the atomic energy industry.

 Application

Dysprosium oxide (Dy2O3) is a rare earth compound with several important applications, particularly due to its unique magnetic properties. Some of its key applications include:

1. Magnets: Dysprosium oxide is used in the production of neodymium-iron-boron (NdFeB) magnets. These magnets are extremely strong and are used in various high-tech applications such as electric vehicles, wind turbines, and hard disk drives.

2. Nuclear Reactors: Dysprosium has a high neutron absorption cross-section, making dysprosium oxide useful in nuclear reactor control rods, where it helps to regulate the nuclear fission process.

3. Lighting: In lighting technology, dysprosium oxide is used in halide lamps to produce a white light that closely resembles natural sunlight, which is beneficial in studios and indoor arenas.

4. Glass and Ceramics: It's used as a coloring agent for glass and ceramics. The oxide can impart a yellowish color to glass and can also be used to create special glass with high optical properties.

5. Research and Electronics: In scientific research, dysprosium oxide is used in various experimental studies, particularly in materials science. It is also used in certain electronic components for its specific electrical properties.

6. Catalysis: Dysprosium oxide can act as a catalyst in certain chemical reactions, particularly in petrochemical refining.

These applications leverage the unique physical and chemical properties of dysprosium oxide, particularly its magnetic characteristics and its ability to absorb neutrons. The demand for dysprosium oxide, like many rare earth elements, has grown with the expansion of high-tech and green technology industries.
