Basic Information
Prodduct Name: Holmium oxide
CAS Number: 12055-62-8
Molecular Formula: Ho2O3
Molecular Weight: 377.88
Appearance: It is a light - yellow crystalline powder, belonging to the isometric - system scandium oxide - type structure. Its color changes significantly depending on the lighting conditions. It appears light yellow under sunlight and intense orange - red under a three - primary - color light source.
Density: 8.16 - 8.36 g/mL (25ºC).
Melting Point: 2330 - 2415ºC.
Boiling Point: 3900ºC.
Solubility: It is insoluble in water, soluble in acids, and easily absorbs carbon dioxide and water when exposed to air.
Uses
Illumination Field: It is used in the manufacture of new - type light sources, dysprosium - holmium lamps. The light emitted by these lamps is similar to sunlight, with a color temperature of 5500K and good color - rendering properties, which can be used to supplement insufficient sunlight in the photography field.
Optical Materials Field: It is used as an additive in yttrium iron or yttrium aluminum garnet to improve the optical properties of the materials. It can also be used to prepare special - colored glass. Glass containing holmium oxide has unique color changes under different lighting conditions.
Spectral Calibration Field: Holmium - containing glass and holmium oxide solutions (usually perchloric acid solutions) have sharp absorption peaks in the spectral range of 200 - 900nm and can be used as standard substances for the calibration of spectrometers.
Laser Materials Field: As a laser material, the wavelength of holmium laser is about 2.08μm, which is harmless to the eyes and can be used in the fields of medicine, optical radar, wind speed measurement, and atmospheric monitoring.
Catalyst Field: Like other rare - earth elements, it can be used as a special - type catalyst in certain chemical reactions to improve the reaction efficiency and selectivity.
Packaging and Storage
Packaging: Usually, it is packed in 25 - kg barrels or can be packaged according to customer requirements.
Storage: It should be stored in a dry and well - ventilated environment, protected from moisture, and kept away from acidic substances and carbon dioxide to prevent it from absorbing carbon dioxide and water and deteriorating.
