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.
Formula: Dy2o3
EINECS: 215-164-0
Classification: Dysprosium Oxide
Purpose: As an additive element of yttrium iron and yttrium aluminum garnet, it can be used as control material of nuclear reactor. It is used to manufacture dysprosium lamp with high brightness and good light color. Because of its cathode emission ability, it can also be used as anode coating. For the metal dysprosium raw material, glass, NdFeb permanent magnet additive, magneto-optical memory material.
