Product Description
Dysprosium oxide is a white powder that is slightly hygroscopic, absorbing water and carbon dioxide in the air. Dysprosium oxide is an important rare earth material, which is widely used. In addition to the atomic energy industry used as a control rod for nuclear reactors, it can also be used for metal halogen lamps, magneto-optical memory materials, glass, NdFeb permanent magnet additives, etc.
