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 Bohr ModelTerbium Element SymbolTerbium (atomic symbol: Tb, atomic number: 65) is a Block F, Group 3, Period 6 element with an atomic radius of 158.92535. The number of electrons in each of Terbium's shells is [2, 8, 18, 27, 8, 2] and its electron configuration is [Xe]4f9 6s2. The terbium atom has a radius of 177 pm and a Van der Waals radius of 221 pm.Terbium was discovered and first isolated by Carl Gustaf Mosander in 1842. In its elemental form, terbium is a silvery-white soft metal. Elemental Terbium Terbium is found in cerite, gadolinite, and monazite. It is not found in nature as a free element. Terbium compounds are brihtly fluorescent, and a majority of the world's terbium supply is used for creating green phosphors that enable trichromatic lighting technology. It is also frequently used as a dopant for crystalline solid-state devices and fuel cell materials. It is named after "Ytterby," the town in Sweden where it was discovered.
