High Purity ChunkAmerican Elements specializes in producing high purity Terbium 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 Terbium as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Terbium(Tb) atomic and molecular weight, atomic number and elemental symbolTerbium is a Block F, Group 3, Period 6 element. The number of electrons in each of Terbium's shells is 2, 8, 18, 27, 8, 2 and its electronic configuration is [Xe]4f9 6s2. In its elemental form terbium's CAS number is 7440-27-9. Terbium is considered to be somewhat toxic. The terbium atom has a radius of 176.3.pm and its Van der Waals radius is unknown. Terbium is primarily used in phosphors, particularly in Terbium Bohr Modelfluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety. In December 2012, a new set of radioactive terbium isotopes developed by a team of scientists from CERN-ISOLDE, the Paul Scherrer Institute, and the Institut Laue-Langevin were shown to effectively target tumors in a successful preclinical study, suggesting that terbium could play a role as a "Swiss Army knife of Nuclear Medicine" in future cancer diagnosis and treatment therapies. Elemental TerbiumTerbium is found in a number of minerals, including cerite, gadolinite, monazite, xenotime, euxenite and bastnaesite.Terbium 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. Terbium responds efficiently in x-ray excitation and is, therefore, used as an x-ray phosphor. Terbium alloys are also used in magneto-optic recording films, such as Tb-Fe-Co. Terbium was first discovered by Carl Mosander in 1843. Terbium is named after "Ytterby", a town in Sweden. See Terbium research below.
