Holmium Oxide Ho2O3

Product Detail

Brief information Product: Holmium Oxide Formula: Ho2O3 Purity:Purity:99.999%(5N), 99.99%(4N),99.9%(3N) (Ho2O3/REO) CAS No.: 12055-62-8 Molecular Weight: 377.86 Density: 1.0966 g/mL at 25 °C Melting point: >100 °C(lit.) Appearance: Light yellow powder Solubility: Insoluble in water, moderately soluble in strong mineral acids Stability: Slightly hygroscopic Multilingual: HolmiumOxid, Oxyde De Holmium, Oxido Del Holmio Application 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). Holmium Oxide is used for making holmium iron alloy, metal holmium, magnetic materials, additives for metal halogen lamps, additives for controlling thermonuclear reaction of yttrium iron or yttrium aluminum garnet, and raw materials for making metal holmium. Holmium Oxide is used as an additive for electric light sources and yttrium iron or gadolinium aluminum garnet, as well as new electric light sources in glass, ceramics, and electronic industries and other aspects. Batch Weight：1000,2000Kg. Packaging：In steel drum with inner double PVC bags containing 50Kg net each. Specification
