Holmium Metal, is mainly used for making speciality alloys and superconductive materials. Holmium is used in Yttrium-Aluminum-Garnet (YAG) and Yttrium-Lanthanum-Fluoride (YLF) solid-state lasers found inmicrowave equipment (which are in turn found in a variety of medical and dental settings). Holmium lasers are used in medical, dental, and fiber-optical applications .Holmium is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring. Holmium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
