American Elements specializes in producing spray dry and non-spray dry high purity Terbium Oxide Powder 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). Powders are 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 Powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron) and our spray dried powder with binder provides an extremely narrow particle size distribution (PSD) for use in thermal and plasma spray guns and other coating applications. We can also provide many materials in the nanoscale range. We also produce Terbium Oxide as pellets, pieces, tablets, and sputtering target. 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. See research below. 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.
