Holmium Oxide (Ho2O3): A Critical Rare Earth Material for Advanced Technologies
Holmium oxide (chemical formula Ho₂O₃), also called holmia, is a rare earth compound with the CAS number 12055-62-8 and EC number 235-015-3. As one of the oxides of the trivalent lanthanides, it is primarily extracted from rare-earth minerals like gadolinite and monazite.
This metal oxide exhibits a light yellow powder appearance under standard lighting conditions, though its tannish yellow color can shift depending on particle size and temperature. With its high melting point (>2,400°C) and insoluble nature in water, Ho2O3 serves as a cornerstone in industries demanding extreme stability and precision.
Key Specifications & Properties of Holmium Oxide (Ho₂O₃)
Certificate of Analysis
Below are the critical properties of holmium oxide that define its industrial and scientific utility:
| Property | Specification |
|---|---|
| Purity | 99.9%–99.999% (high purity) |
| Density | 8.41 g/cm³ |
| Particle Size | Customizable (nanopowder to microns) |
| CAS Number | 12055-62-8 |
| Linear Formula | Ho₂O₃ |
| Optical Properties | Sharp emission bands at 450–470 nm |
| Certifications | Certificate of Analysis (COA) provided |
Holmium oxide powder is chemically inert but oxidizes in air at elevated temperatures. Its magnetic properties stem from holmium in nature, which is one of the most powerfully paramagnetic substances known.
Holmium Oxide vs. Alternative Rare Earth Materials: Competitive Advantages
While holmium oxide (Ho₂O₃) shares similarities with other rare earth oxides, its niche advantages make it irreplaceable in specific contexts:
| Feature | Ho₂O₃ | Alternatives (e.g., Er₂O₃, Dy₂O₃) |
|---|---|---|
| Neutron Absorption | Exceptional (used in nuclear reactors) | Moderate |
| Thermal Stability | Stable up to 2,400°C | Lower melting points |
| Optical Efficiency | Sharp optical absorption peaks | Broader spectral bands |
| Specialized Uses | Laser materials, ceramics-based magneto-optical materials | Limited to generic magnetic materials |
Ho₂O₃’s ability to act as a dopant in solid-state devices further exclude substitutes in advanced electronics and medical technologies.
