American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. American Elements specializes in producing Indium High Purity Foil and sheets in many thicknesses and sizes for numerous industrial uses and provides health and occupational safety information for this product. Most foils are produced from cast Ingots for use in coating and thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.003" to approximately 2mm for all metals. Some metals can also be rolled down as thin as 0.001" for use as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings. Piece sizes are available up to approximately 7" maximum width. Maximum lengths of about 20" can be obtained with a nominal thickness between about 0.005" and 0.020" for thin film deposition on glass or metal substrates. 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 and in the form of solutions and organometallics. We also produce Indium as rods, powder and plates. Other shapes are available by request.

See more Indium products. Indium (atomic symbol: In, atomic number: 49) is a Block P, Group 13, Period 5 element with an atomic weight of 114.818. The number of electrons in each of indium's shells is [2, 8, 18, 18, 3] and its electron configuration is [Kr] 4d10 5s2 5p1. The indium atom has a radius of 162.6 pm and a Van der Waals radius of 193 pm. Indium was discovered by Ferdinand Reich and Hieronymous Theodor Richter in 1863. Indium Bohr ModelIt is a relatively rare, extremely soft metal is a lustrous silvery gray and is both malleable and easily fusible. It has similar chemical properties to Elemental Indiumgallium such as a low melting point and the ability to wet glass. Fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium, especially in the form of Indiun Tin Oxide (ITO). Thin films of Copper Indium Gallium Selenide (CIGS) are used in high-performing solar cells. Indium's name is derived from the Latin word indicum, meaning violet.
