Safety Data Sheet

American Elements specializes in supplying Osmium Crucibles Crucible Packaging, Lab Quantitywith 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 (Os) atomic and molecular weight, atomic number and elemental symbolOsmium (atomic symbol: Os, atomic number: 76) is a Block D, Group 8, Period 6 element with an atomic weight of 190.23.Osmium Bohr Model The number of electrons in each of osmium's shells is [2, 8, 18, 32, 14, 2] and its electron configuration is [Xe] 4f14 5d6 6s2. The osmium atom has a radius of 135 pm and a Van der Waals radius of 216 pm. Osmium was discovered and first isolated by Smithson Tennant in 1803. Elemental Osmium In its elemental form, osmium has a silvery blue cast apperance. Osmium has the highest melting point and the lowest vapor pressure of any of the platinum group of metals; it is also the densest naturally ocurring element.. Osmium is the least abundant stable element in the earth's crust. It is found in the alloys osmiridium and iridiosmium and as a free element. The origin of the name Osmium comes from the Greek word "osme," meaning a smell or odor.
