Holmium Oxide

Holmium Oxide/Holmium(III) Oxide/Ho2O3/Holmia Powder 12055-62-8

Holmium(III) Oxide, or Holmium Oxide is a highly insoluble thermally stable Holmium source. It is a chemical compound of a rare-earth element holmium and oxygen with the formula Ho2O3. Holmium oxide occurs in small quantities in the minerals monazite, gadolinite, and in other rare-earth minerals. Holmium metal easily oxidizes in air; therefore presence of holmium in nature is synonymous with that of holmium oxide. It is suitable for glass, optic and ceramic applications.

What is Holmium Oxide used for?

Holmium Oxide is one of the colorants used for cubic zirconia and glass, as a calibration standard for optical spectrophotometers, as a specialty catalyst, phosphor and a laser material, providing yellow or red coloring. It is used in making specialty colored glasses. Glass containing holmium oxide and holmium oxide solutions have a series of sharp optical absorption peaks in the visible spectral range. As most other oxides of rare-earth elements, holmium oxide is used as a specialty catalyst, phosphor and a laser material. Holmium laser operates at wavelength of about 2.08 micrometres, either in pulsed or continuous regime. This laser is eye safe and is used in medicine, lidars, wind velocity measurements and atmosphere monitoring. Holmium can absorb fission-bred neutrons, it is also used in nuclear reactors to keep atomic chain reaction from running out of control.
