 American Elements specializes in producing high purity uniform shaped Samarium Oxide Pellets with the highest possible density  and smallest possible average grain sizes 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). Our standard Pellet sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Pellets outside this range for ultra high purity thin film applications, such as fuel cells and solar energy layers. 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 (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Samarium as pieces, tablets, powder, and sputtering target. Oxide compounds are not conductive to electricity. Other shapes are available by request.
 Samarium is a Block F, Group 3, Period 6 element. The number of electrons in each of Samarium's shells is 2, 8, 18, 24, 8, 2 and its electronic configuration is [Xe]4f6 6s2. In its elemental form samarium's CAS number is 7440-19-9. The samarium atom has a radius of 180.4.pm and it's Van der Waals radius is unknown. Samarium is somewhat toxic. Samarium is primarily utilized in the production of samarium-cobalt (Sm2Co17) permanent magnets. Samarium 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. It is also used in laser applications and for its dielectric properties. Samarium-cobalt magnets replaced the more expensive platinum-cobalt magnets in the early 1970s. While now overshadowed by the less expensive neodymium-iron-boron magnet, they are still valued for their ability to function at high temperatures. They are utilized in lightweight electronic equipment where size or space is a limiting factor and where functionality at high temperature is a concern. Applications include electronic watches, aeospace equipment, microwave technology and servomotors. Because of its weak spectral absorption band samarium is used in the filter glass on Nd:YAG solid state lasers to surround the laser rod to improve efficiency by absorbing stray emissions. Samarium was first discovered by Paul Emile Lecoq de Boisbaudran in 1879. Samarium is named after the mineral samarskite. See Samarium research below.
