Gadolinium Oxide (Gd2O3): A Critical Rare Earth Material for Advanced Technologies
Gadolinium oxide (Gd2O3), also known as gadolinia or digadolinium trioxide, is a versatile rare-earth compound with exceptional magnetic, optical, and thermal properties.
As an authorized supplier under China Rare Earth Group, Ruisen provides high-purity gadolinium oxide powder to industries and research institutions worldwide, ensuring efficient identification and quality control through rigorous testing and certificate of analysis documentation.
Key Properties & Specifications of High-Purity Gadolinium Oxide
Certificate of Analysis
Gadolinium oxide (Gd₂O₃) is characterized by its cubic crystal structure (space group Ia-3) and insoluble nature in water. Below are its critical specifications:
| Property | Value |
|---|---|
| Chemical Formula | Gd₂O₃ |
| CAS Number | 12064-62-9 |
| EC Number | 235-060-9 |
| Linear Formula | Gd₂O₃ |
| Purity Grades | 99.9%, 99.99%, 99.999% |
| Particle Size | 50–200 nm (customizable) |
| Density | 7.41 g/cm³ |
| Commonly Available Forms | Nanoparticle, powder, coating |
This oxide is produced via thermal decomposition of the hydroxide or carbonate derivatives, ensuring minimal anion contamination. All batches are clearly tagged and labeled externally to ensure efficient identification and quality compliance.
Gadolinium Oxide (Gd₂O₃) vs. Alternatives: Performance Advantages at a Glance
While ceria (CeO₂) and neodymium or erbium oxides are commonly used in similar applications, Gd₂O₃ offers unique advantages:
| Property | Gd₂O₃ | Alternatives |
|---|---|---|
| Thermal Stability | Stable up to 2350°C | Lower melt points (e.g., CeO₂: 2400°C) |
| Neutron Absorption | High cross-section (48 kb) | Moderate absorption |
| Magnetic Properties | Strong paramagnetic behavior | Limited magnetic response |
Its ionic conductivity and ability to dope materials like gadolinium yttrium garnets make it irreplaceable in solid oxide fuel cells and laser technologies.
Innovative Applications of Gd2O3 in Key Industries
1. Medical Imaging
Gadolinium oxide is used to synthesize contrast agents for magnetic resonance imaging (MRI). Its rare-earth ions enhance luminescence in multimodal imaging systems, improving detector sensitivity.
2. Nuclear Energy
As a neutron absorb material, Gd2O3 stabilizes reactor operations. Its thermal resilience avoids premature decomposition under extreme conditions.
3. Electronics & Optics
Gadolinium oxide nanoparticles act as host material in phosphors for LEDs and optical glass. They also dope electrolyte layers in fuel cells to boost energy conversion efficiency.
4. Catalysis
The chemical stability of Gd2O3 supports scientific breakthroughs in electrochemical sensors and nanomaterials synthesis.
How Gadolinium Oxide Drives Scientific Breakthroughs
Researchers leverage Gd2O3’s property portfolio for:
- Quantum Computing: Gadolinium-doped crystals enable precise control of rare-earth ions.
- Radiation Shielding: Tripodal and triangular gadolinium oxide structures improve X-ray attenuation.
- Telecommunications and Medical: Gadolinium sesquioxide enhances fiber optic signal clarity at specific wavelengths.
