Key Properties & Specifications of Erbium Oxide (Er₂O₃)
Certificate of Analysis
Er₂O₃ is a pink powder with a hexagonal or cubic crystal structure, known for its high dielectric constant and large band gap. Below are its core specifications:
| Property | Specification |
|---|---|
| Chemical Formula | Er₂O₃ |
| Purity | 99.9% (3N), 99.99% (4N) |
| Particle Size | 50 nm – 5 µm (customizable) |
| Density | 8.64 g/cm³ |
| Solubility | Insoluble in water, readily reacts with acids |
| Stability | Stable at high temperatures; resists moisture and carbon dioxide |
This compound exhibits exceptional photoluminescence property, making it ideal for fiber optics and laser systems. Its nanoscale form, erbium oxide nanoparticles, is surface-modified for enhanced distribution into aqueous and non-aqueous media, crucial for biomedical applications.
Er₂O₃ vs. Alternatives: Comparative Advantages
Er₂O₃ outperforms substitutes like Y₂O₃ or Al₂O₃ in niche applications. Here’s a competitive comparison:
| Feature | Er₂O₃ | Alternatives |
|---|---|---|
| Thermal Stability | Stable up to 2,300°C | Y₂O₃: 2,400°C |
| Neutron Absorption | High (neutron poison for nuclear fuel) | Low in most oxides |
| Optical Efficiency | Superior erbium ions emission | Limited in non-lanthanide materials |
| Cost-Effectiveness | Optimal for specialized uses | Lower upfront cost |
Er₂O₃’s unique chemical and electrical properties solidify its role in semiconductor doping and gate dielectrics.
