Cas no 12055-62-8 (Holmium(III) oxide)

Holmium(III) oxide (Ho?O?) is a high-purity rare earth compound with a cubic crystal structure, known for its exceptional thermal and chemical stability. It exhibits strong paramagnetic properties, making it valuable in specialized magnetic and optical applications. The oxide is highly insoluble in water but soluble in acids, facilitating its use in synthetic chemistry. Its sharp absorption peaks in the visible and near-infrared spectra are leveraged in laser and glass doping to achieve precise wavelength control. Ho?O? is also employed in nuclear reactors as a neutron absorber due to its high neutron capture cross-section. Its consistent purity (>99.9%) ensures reliable performance in research and industrial settings.
