American Elements specializes in producing high purity Cesium Shot with the highest possible density and smallest possible average grain sizes for use in semiconductor, 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). Our standard Shot sizes range from 1-3mm . We can also provide Shot outside this range for ultra high purity thin film applications, such as fuel cells and solar energy layers. 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 Cesium as rod , ingot , powder , pieces , disc , granules , wire , and in compound forms, such as oxide . Other shapes are available by request.

Cesium is a Block S, Group 1, Period 6 element. The electronic configuration is [Xe] 6s¹. In its elemental form cesium's CAS number is 7440-46-2. The cesium atom has a radius of 265.5.pm and it's Van der Waals radius is 200.pm. Cesium is a member of the alkali group of metals. It is one of three metals that occur as a liquid at room temperature - the others are mercury and gallium. Cesium 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. Cesium is used as an oxygen "getter" in vacuum and electronic tubes and as a component of photoelectric cells.
