HOLMIUM Usage And Synthesis
DescriptionHolmium has the highest magnetic moment (10.6uB) of any naturally occurring element. Because of this it has been used to create the highest known magnetic fields by placing it within high strength magnets as a pole piece or magnetic flux concentrator. 
This magnetic property also has value in Yttrium-Iron-Garnet (YIG) lasers for microwave equipment.
Holmium lasers emit at a human eye safe 2.08 microns allowing its use in a variety of medical and dental applications in both Yttrium-Aluminum-Garnet (YAG) and Yttrium-Lanthanum-Fluoride (YLF) solid state lasers. The wavelength allows for use in silica fibers designed for shorter wavelengths while still providing the cutting strength of longer wave length equipment.
Holmium is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring.
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.
Chemical Propertiesgrey metal ingot
HistoryThe spectral absorption bands of holmium were noticed in 1878 by the Swiss chemists Delafontaine and Soret, who announced the existence of an “Element X.” Cleve, of Sweden, later independently discovered the element while working on erbia earth. Holmium is named after Cleve’s native city. Pure holmia, the yellow oxide, was prepared by Homberg in 1911. Holmium occurs in gadolinite, monazite, and in other rare-earth minerals. It is commercially obtained from monazite, occurring in that mineral to the extent of about 0.05%. It has been isolated by the reduction of its anhydrous chloride or fluoride with calcium metal. Pure holmium has a metallicto bright silver luster. It is relatively soft and malleable, and is stable in dry air at room temperature, but rapidly oxidizes in moist air and at elevated temperatures. Holmium has unusual magnetic properties. Few uses have yet been found for the element. The element, as with other rare earths, seems to have a low acute toxic rating. Natural holmium consists of one isotope 165Ho, which is not radioactive. Holmium has 49 other isotopes known, all of which are radioactive. The price of 99.9% holmium metal is about $20/g.
UsesGetter in vacuum tubes, research in electrochemistry, spectroscopy.
DefinitionMetallic element of atomic number 67, group IIIB of the periodic table, one of the rare-earth elements of the yttrium subgroup, aw 164.9303, valence of 3, no stable isotopes.
