About Holmium Spring

Holmium SpringThe most common type of spring is the coil spring; however, a spring can be any elastic object that can store energy. Holmium Springs are helix shaped springs that can store and release mechanical energy, absorb shock, or maintain a force between contacting surfaces. American Elements specializes in producing high purity uniform shaped Holmium Spring with the highest possible density for use in semiconductor, 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 springs store and release mechanical energy, absorb shock, and conserve force between contacting surfaces. Our standard Metal Spring sizes range from 0.75 mm to 1 mm to 2 mm diameter with strict tolerances and alpha values (conductive resistance) for uses such as gas detection and thermometry tolerances (Also see Nanoparticles) . Please contact us to fabricate custom spring alloys and gauge sizes. 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 can also provide Rod outside this range. We also produce Holmium as powder, ingot, pieces, pellets, disc, granules and in compound forms, such as oxide. Other shapes are available by request. Holmium springs can have several different purposes.

Holmium Bohr ModelThe number of electrons in each of Holmium's shells is [2, 8, 18, 29, 8, 2] and its electron configuration is [Xe] 4f11 6s2. Elemental Holmium PictureThe 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. 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.
