Dysprosium Oxide Dy2O3 CAS 1308-87-8 For NdFeB additive

Dysprosium oxide is a white powdery rare earth oxide with high melting point and good chemical stability. It is insoluble in water, but soluble in inorganic acids, easy to absorb carbon dioxide from the air into dysprosium carbonate. In the field of optics, dysprosium oxide is used to manufacture optical glasses with high refractive index and low scattering loss to improve the performance of optical instruments. In the laser field, it is a key component of laser crystals, which facilitates the manufacture of high-performance solid-state lasers. In addition, dysprosium oxide is an important magnetic material that can be used in the production of permanent magnets and magnetic storage media. In the field of catalysis, it catalyzes oxidation and dehydrogenation reactions to improve reaction efficiency.
