Germanium ScrapsGermanium recycling is the process by which Germanium scrap can be reused in products after its initial production. Scrap metals are recycled from many common residential, commercial, and industrial items that would otherwise be thrown away. American Elements specializes in producing irregular shaped Germanium Scraps with the highest possible density and smallest possible average grain sizes for use in 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). Germanium scrap is available in varying grades and dimensions. 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 Germanium as rod, ingot, powder, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request. As much as 60% of the metals and alloys produced in the U.S. are recycled. Germanium scrap prices vary depending on market conditions and grade.

Germanium (Ge) atomic and molecular weight, atomic number and elemental symbolGermanium (atomic symbol: Ge, atomic number: 32) is a Block P, Group 14, Period 4 element with an atomic weight of 72.63. Germanium Bohr ModelThe number of electrons in each of germanium's shells is 2, 8, 18, 4 and its electron configuration is [Ar] 3d10 4s2 4p2. The germanium atom has a radius of 122.5 pm and a Van der Waals radius of 211 pm. Germanium was first discovered by Clemens Winkler in 1886. In its elemental form, germanium is a brittle grayish white semi-metallic element. Germanium is too reactive to be found naturally on Earth in its native state.High Purity (99.999%) Germanium (Ge) Metal It is commercially obtained from zinc ores and certain coals. It is also found in argyrodite and germanite. It is used extensively as a semiconductor in transitors, solar cells, and optical materials. Other applications include acting an alloying agent, as a phosphor in fluorescent lamps, and as a catalyst. The name Germanium originates from the Latin word "Germania" meaning "Germany," For more information on germanium, including properties, safety data, research, and American Elements' catalog of germanium products, visit the Germanium Information Center.
