Holmium oxide (CAS 12055-62-8) is a specialized rare earth compound valued for its unique optical properties, particularly in infrared lasers (e.g., Ho:YAG lasers) used in medical surgery and cutting applications. It serves as a dopant in optical fibers and glass to enhance infrared transmission. In nuclear reactors, it acts as a neutron absorber due to its high capture cross-section. The compound also finds use in colored glass (pink/yellow hues) and calibration standards for spectrophotometers. Available as a yellow-brown powder, Ho2O3 is stable but hygroscopic, requiring airtight storage. Proper handling with PPE is recommended to avoid dust inhalation. |
