American Elements specializes in producing high purity Praseodymium Oxide Shot 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 Shot sizes range from 1-3mm . We can also provide Shot 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. See research below. We also produce Praseodymium Oxide as rod , ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.
Praseodymium is a Block F, Group 3, Period 6 element. The number of electrons in each of Praseodymium's shells is 2, 8, 18, 21, 8, 2 and its electronic configuration is [Xe]4f3 6s2. In its elemental form praseodymium's CAS number is 7440-10-0. The praseodymium atom has a radius of 182.pm and it's Van der Waals radius is is unknown. Praseodymium is somewhat toxic. Praseodymium resembles the typical trivalent rare earths, however, it will
exhibit a +4 state when stabilized in a zirconia host. Praseodymium 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. The element is found in most all light rare earth derivatives. It is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Much research is being done on its optical properties for use in amplification of telecommunication systems, including as a doping agent in fluoride fibers. The origin of the element name comes from the Greek words 'prasios didymos' meaning green twin. See Praseodymium research below.
