Safety Data Sheet

High Purity Chunk American Elements specializes in producing high purity Osmium Chunk using crystallization, solid state and other ultra high purification processes such as sublimation. Standard Chunk pieces are amorphous uniform pieces ranging in size from 5-15 mm. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into granules, rod, bar or plate form, as well as other 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. We also produce Osmium as rod, pellets, powder, pieces, disc, 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.
