    Holmium Oxide Powder Introduction

    Holmium (III) oxide, also known as Holmia, is a light yellow powder that is one of the most paramagnetic substances known. Holmium Oxide has specialized uses in ceramics, glass, phosphors, and metal halide lamps, and dopant to the garnet laser. Holmium can absorb fission-bred neutrons. It is also used in nuclear reactors to keep the 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 colors used for cubic zirconia and glass, providing yellow or red coloring. It is also used in Yttrium-Aluminum-Garnet (YAG) and Yttrium-La-Fluoride (YLF) solid-state lasers found in microwave equipment (which are found in a variety of medical and dental settings).
