Holmium Dust Holmium dust is composed of fine grained granular material. The dust form of some elements can be highly combustible as a result of its high surface area. American Elements specializes in producing high purity Holmium Dust with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Holmium dust is composed of large free flowing particles. Dusts are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles () also produce very high surface areas. Our standard Dust particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range. 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 such as nanoparticles () and in the form of solutions and organometallics. We also produce Holmium as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request. Holmium dust has a wide range of bulk densities, becoming light and fluffy when loosened or dense and unable to flow when compressed. Dusts have been studied by chemical engineers, mechanical engineers, chemists, physicists and geologists on account of their importance to industry, medicine, and earth science.

Holmium Bohr ModelHolmium Element SymbolHolmium (atomic symbol: Ho, atomic number: 67) is a Block F, Group 3, Period 6 element with an atomic radius of 164.93032. The number of electrons in each of Holmium's shells is [2, 8, 18, 29, 8, 2] and its electron configuration is [Xe] 4f11 6s2. The holmium atom has a radius of 176 pm and its Covalent radius is 192±7 pm. Holmium was first discovered by Marc Delafontaine in 1878. Elemental Holmium Picture In its elemental form, holmium has a silvery white appearance. It is relatively soft and malleable. It is stable in dry air at room temperature but rapidly oxidizes at elevated temperatures and in moist air. Holmium has unusual magnetic properties. Its name is derived from the Latin word Holmia meaning Stockholm.
