American Elements specializes in producing spray dry and non-spray dry high purity Palladium 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 Palladium 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 safety data and research below and pricing/lead time above. Other shapes are available by request.
Palladium is a Block D, Group 10, Period 5 element. The number of electrons in each of Palladium's shells is 2, 8, 18, 18 and its electronic configuration is [Kr] 4d10. In its elemental form palladium's CAS number is 7440-05-3. The palladium atom has a radius of 137.6.pm and it's Van der Waals radius is 163.pm. Palladium is a member of the platinum group of metals. It is an excellent hydrogenation and dehydrogenation catalyst and available in many Organo-metallic forms for this purpose. It is alloyed with gold, silver, iridium and other platinum group elements and used in jewelry. The metal is used in dentistry, watch making, and in making surgical instruments and electrical contacts. Platinum 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. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below.
