Holmium Oxide Ho2O3 Holmia glass filter CAS NO.12055-62-8
Product Description
Holmium oxide, also known as holmium trioxide, chemical formula Ho2O3, is a compound composed of rare earth element holmium and oxygen element, and dysprosium oxide is one of the strongest known paramagnetic substances. Holmium oxide is one of the constituents of the erbium oxide mineral. In its natural state, holmium oxide often coexists with trivalent oxides of lanthanides, requiring special methods to separate them. Holmium oxide can be used to make special colored glass. The visible absorption spectra of glasses and solutions containing holmium oxide have a series of sharp peaks and are therefore traditionally used as standards for calibration of spectrometers.
Uses: It is used in the manufacture of new light source dysprosium holmium lamps, and can also be used as an additive for yttrium iron to obtain yttrium aluminum garnet and for the preparation of metal holmium.
Holmium oxide can be used as a yellow and red colorant for Soviet diamonds and glass. Glass containing holmium oxide and holmium oxide solution (usually perchloric acid solution) have sharp absorption peaks in the range of 200-900 nm, so they can be used as standards for spectrometer calibration and have been commercialized. Like other rare earth elements, holmium oxide is used as a specialty catalyst, phosphor, and laser material. The holmium laser has a wavelength of about 2.08 μm and can be either pulsed or continuous light. The laser is harmless to the eyes and can be used in medicine, lidar, wind speed measurement and atmospheric monitoring.
