High Purity ChunkAmerican Elements specializes in producing high purity Samarium Chunk using crystallization, solid state and other ultra high purification processes such as sublimation. Standard Chunk pieces are amorphous uniform pieces ranging in size from 5-15 mm. 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 granules, 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. See research below. We also produce Samarium as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Samarium(Sm)atomic and molecular weight, atomic number and elemental symbol 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. 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. Samarium is somewhat toxic. Samarium-cobalt magnets replaced the more expensive platinum-cobalt magnets in the early 1970s. While now overshadowed by less expensive neodymium-iron-boron magnets, 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. Samarium Bohr Model 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 Elemental Samarium surround the laser rod to improve efficiency by absorbing stray emissions. In separate December 2012 experiments, researchers at the University of Michigan, the University of Maryland, and the University of California, Irvine found that Samarium hexaboride may have the ability to act as a topological insulator, an insulating substance with surface conductivity whose existence has been predicted by quantum theory but never observed by scientists. Samarium, first discovered by Paul Emile Lecoq de Boisbaudran in 1879, is found in many minerals, including monazite, bastnäsite, cerite, gadolinite and samarskite. Samarium is named after the mineral samarskite. See Samarium research below.
