American Elements specializes in supplying Osmium Crucibles with a variety of dimensions including round, in numerous standard diameters and wall thicknesses. Custom configurations are available. Materials include most metals including most transition, refractory and precious metals and other advanced materials. Crucibles can also be produced from custom materials and alloys for commercial and research applications and for new proprietary technologies. Other available shapes include tubes, bar or plate form, as well as custom machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots ) and in the form of solutions and organometallics . See research below. We also produce Osmium as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

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 its Van der Waals radius is 200.pm. Osmium has the highest melting point and the lowest vapor pressure ofany of the platinum group of metals. The metal is almost entirely used to produce very hard alloys with other metals of the platinum group. In 2013, researchers from the Ruhr University Bocham and the National University of Ireland, Galway synthesized a new type of redox polymer containing osmium that shows promise as an enzyme for glucose-oxidizing enzyme electrodes in biosensors or biofuel cells. Osmium in the form of tetroxide (OsO₄) is very toxic and can cause eye, lung and skin damage. Osmium tetroxide has recently been used to detect fingerprints and as an aid to stain fatty tissue for microscope slides. 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, the least abundant stable element in the earth's crust, is found in the alloys osmiridium and iridiosmium and as an uncombined element. 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.
