Lanthanum Oxide (La2O3): A High-Performance Rare Earth Compound
Lanthanum oxide (chemical formula La₂O₃), also known as lanthanum trioxide or lanthanum sesquioxide, is a critical rare earth oxide with the CAS 1312-81-8.
This versatile compound serves as a cornerstone in advanced technologies, from optical materials to solid-state electronics. Its unique crystal structure, characterized by a hexagonal lattice and an empty ln-4f shell, enables exceptional basicity and adsorption capabilities.
As a precursor to lamox fast ion conductors, La2O3 is indispensable in developing fuel cells and superconductors.
Key Properties & Specifications of Lanthanum Oxide
Below are the core attributes that define lanthanum oxide powder:
Analytical Report
| Property | Specification |
|---|---|
| Chemical Formula | La₂O₃ |
| Purity | 99.9% (standard), 99.99% (ACS grade) |
| Particle Size | 50 nm – 5 µm (customizable) |
| Density | 6.51 g/cm³ |
| Melting Point | 2,315 °C |
| Solubility | Insoluble in water; reacts with acids |
| Thermal Stability | Stable up to 1,800 °C |
The material’s high surface area and controllable morphology (spherical, nanotube, or composite) make it ideal for chemical synthesis and evaporation processes.
Competitive Advantages of La₂O₃ Over Alternative Materials
Lanthanum oxide outperforms alternatives like ceria (CeO2) and yttrium oxide in multiple domains:
| Feature | La₂O₃ | CeO2 |
|---|---|---|
| Thermal Conductivity | Low (0.7 W/m·K) | High (10 W/m·K) |
| Hardness | 5.5 Mohs | 6.0 Mohs |
| Catalytic Efficiency | Superior in recyclable catalytic systems | Limited by Ce4+ cation instability |
| Cost-Efficiency | High yield per mol | Requires reducing agents |
La₂O₃’s wide band gap (5.4 eV) and p-type semiconductor properties further distinguish it in electronics and optical fibers.
