American Elements specializes in producing Ytterbium as plates in various thicknesses and sizes. Most plates are cast 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. Thicknesses start at 0.25" for all metals. 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 Ytterbium as rods, powder and plates. Other shapes are available by request.

Related Products & Element Information

See more Ytterbium products. Ytterbium (atomic symbol: Yb, atomic number: 70) is a Block F, Group 3, Period 6 element with an atomic weight of 173.054. Ytterbium Bohr ModelThe number of electrons in each of Ytterbium's shells is [2, 8, 18, 32, 8, 2] and its electron configuration is [Xe]4f14 6s2. The Ytterbium atom has a radius of 176 pm and a Van der Waals radius of 242 pm. Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878 and first isolated by Georges Urbain in 1907.Elemental Ytterbium In its elemental form, ytterbium has a silvery-white color. Ytterbium is found in monazite sand as well as the ores euxenite and xenotime. Ytterbium is named after Ytterby, a village in Sweden. Ytterbium can be used as a source for gamma rays, for the doping of stainless steel, or other active metals. Its electrical resistivity rises under stress, making it very useful for stress gauges that measure the deformation of the ground in the even of an earthquake.
