Dysprosium Oxide (Dy2O3): A Critical Rare Earth Material for Advanced Technologies
Dysprosium oxide, also known as dysprosia, is a sesquioxide compound of the rare earth metal dysprosium, with the CAS 1308-87-8. As a high purity rare earth oxide, it plays a pivotal role in advanced materials driving innovations across aerospace, energy, and electronics.
Its unique magnetic and thermal properties make it indispensable for high-performance applications, from NdFeB magnets in electric vehicles to optical coatings in laser systems. With global demand surging, Dy2O3 stands at the forefront of sustainable technology development.
Key Characteristics and Technical Specifications of Dysprosium Oxide
Certificate of Analysis
Dysprosium oxide powder is characterized by its white powder appearance, crystalline structure, and slightly hygroscopic nature. Below are its core specifications:
| Property | Value |
|---|---|
| Chemical Formula | Dy₂O₃ |
| Purity | 99.9% (3N), 99.99% (4N) |
| Particle Size | <50 nm (customizable) |
| Melting Point | 2,408°C |
| Density | 7.81 g/cm³ |
