Holmium Oxide (Ho2O3) Powder

Product Code : RE-Ho2O3-5N-PO

Holmium Oxide is a highly insoluble thermally stable Holmium source suitable for glass, optic and ceramic applications. 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.

Holmium Oxide

Holmium Oxide is a highly insoluble thermally stable Holmium source suitable for glass, optic and ceramic applications. 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. Holmium Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Holmium has the highest magnetic moment (10.6 µB) of High Purity (99.999%) Holmium Oxide (Ho2O3) Powderany naturally occurring element and has been used to create the highest known magnetic fields as a pole piece or magnetic flux concentrator. Oxide compounds are not conductive to electricity.Holmium Oxide, also called Holmia, has specialized uses in ceramics, glass, phosphors and metal halide lamp, and dopant to the 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).
