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).
