Description
Holmium Oxide Ho2O3 Powder Properties
Performance of Holmium Oxide Ho2O3 Powder :
Holmium oxide, also known as holmium trioxide, chemical formula Ho2O3, is a compound composed of the rare earth element holmium and oxygen element, and dysprosium oxide is one of the strongest known paramagnetic substances. Holmium oxide is one of the components of erbium oxide minerals. In its natural state, holmium oxide often coexists with trivalent oxides of lanthanides, and it requires a special method to separate them. Holmium oxide can be used to prepare special colored glass. The visible absorption spectrum of glass and solutions containing holmium oxide has a series of sharp peaks, so it is traditionally used as a standard for spectrometer calibration.

Application of Holmium Oxide Ho2O3 Powder :
Holmium Oxide, also called Holmia, has specialized uses in ceramics, glass, phosphors and metal halide lamp, and dopant to garnet laser. Holmium can absorb fission-bred neutrons, it is also used in nuclear reactors to keep atomic chain reaction from running out of control. Holmium Oxide is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring. It is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring. It is also used in Yttrium-Aluminum-Garnet (YAG) and Yttrium-Lanthanum-Fluoride (YLF) solid-state lasers found in microwave equipment (which are in turn found in a variety of medical and dental settings).
