American Elements produces metallic Holmium Ingots with the highest possible density. Ingots are generally the least costly metallic form and useful in general applications. Our standard Ingot size is nominally 2-3 cm x 3-8 cm x 6-12 cm. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes nanoparticles. We can also provide Pieces and Shot in smaller ranges. We also produce Holmium as rod, pellets, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

Holmium(Ho)atomic and molecular weight, atomic number and elemental symbolHolmium is a Block F, Group 3, Period 6 element. The number of electrons in each of Holmium's shells is 2, 8, 18, 29, 8, 2 and its electronic configuration is [Xe] 4f11 6s2. In its elemental form holmium's CAS number is 7440-60-0. The holmium atom has a radius of 174.3.pm and it's Van der Waals radius is unknown. Holmium is only slightly toxic. Holmium has the highest magnetic moment (10.6µB) of any naturally occurring Elemental Holmiumelement. 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-garnetHolmium Bohr Model(YIG) lasers for microwave equipment. Holmium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Holmium lases 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 was first discovered by J.L. Soret in 1878. See Holmium research below.
