Germanium ConcentrateAmerican Elements offers germanium concentrate with a majority germanium base component. Preparation of germanium concentrate typically involves the removal of water from an germanium solution. American Elements specializes in producing high purity Germanium Concentrate with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and 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 concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles (See also Nanotechnology Information and Quantum Dots) also produce very high surface areas. Our standard Concentrate particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range. See safety data and research below and pricing/lead time above. We also produce Germanium as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request. Germanium concentrate is advantageous for transportation since it reduces weight and volume. A solution can be reproduced at the time of usage with the addition of a solvent.

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.
