Osmium Oxide is a highly insoluble thermally stable Osmium source suitable for glass, optic and ceramic applications. Osmium oxide is a volatile pale yellow solid with an acrid odor that disolves in water to form osmic acid.
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. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal oxide compounds are basicanhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Osmium Oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). See Nanotechnology for more nanotechnology applications information. Osmium Oxide is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available.
Osmium is a Block D, Group 8, Period 6 element. The number of electrons in each of Osmium's shells is 2, 8, 18, 32, 14, 2 and its electronic configuration is [Xe] 4f14 5d6 6s2. In its elemental form osmium's CAS number is 7440-04-2. The osmium atom has a radius of 133.8.pm and it's Van der Waals radius is 200.pm. Osmium tetroxide (OsO4) can cause eye, lung and skin damage which makes it very toxic. Osmium has the highest melting point and the lowest vapor pressure of any of the platinum group of metals. Osmium tetroxide has recently been used to detect fingerprints and as an aid to stain fatty tissue for microscope slides. The metal is almost entirely used to produce very hard alloys with other metals of the platinum group. Osmium 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. Osmium was first discovered by Smithson Tennant in 1803. The origin of the name Osmium comes from the Greek word osme meaning a smell or odor. See Osmium research below.
