See research below. American Elements specializes in producing high purity Terbium Oxide rotatable sputtering targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, photovoltaic, and coating applications by chemical vapor deposition (CVD) and physical vapor deposition (PVD) and optical applications. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Our standard Rotatable Targets for large area thin film deposition are produced either by spray coating on a tubular substrate or casting of a solid tube. Rotary Targets are available with dimensions and configurations up to 1,000 mm in length for large area coating for solar energy or fuel cells and flip-chip applications. Research sized targets are also produced as well as custom sizes and alloys. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. Besides rotary targets we can also provide targets outside in just about any size and shape, such as rectangular, annular, or oval targets. 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 nanoparticles. We also produce Terbium as disc, granules, ingot, oxide pellets, oxide pieces, oxide powder, and rod. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Other shapes are available by request.
Terbium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f96s2. In its elemental form terbium's CAS number is 7440-27-9. The terbium atom has a radius of 176.3.pm and it's Van der Waals radius is unknown. Terbium is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety. Terbium 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. Terbium responds efficiently in x-ray excitation and is, therefore, used as an x-ray phosphor. Terbium alloys are also used in magneto-optic recording films, such as Tb-Fe-Co. Terbium was first discovered by Carl Mosander in 1843. |
