American Elements specializes in supplying Iridium 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 Iridium as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Iridium(Ir) atomic and molecular weight, atomic number and elemental symbolIridium is a Block D, Group 9, Period 6 element. The number of electrons in each of Iridium's shells is 2, 8, 18, 32, 15, 2 and its electronic configuration is [Xe] 4f14 5d7 6s2. In its elemental form iridium's CAS number is 7439-88-5. The iridium atom has a radius of 135.7.pm and its Van der Waals radius is 200.pm. Iridium is only slightly toxic. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known. It will not react Iridium Bohr Modelwith any acid and can only be attacked Elemental Iridiumby certain molten salts, such as molten sodium chloride. It is alloyed with platinum to produce highly corrosive resistant electrical contacts for spark plugs. Based on their 2013 research into the magnetic properties of Strontium Iridium Oxide, scientists at the Institute of Physical and Chemical Research (RIKEN) suggest that oxide compounds of heavier transition metals that contain Iridium may have powerful superconducting abilities that are yet to be discovered. Iridium 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. Iridium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed here. Iridium is found as an uncombined element and in iridium-osmium alloys. Iridium was first discovered by Smithson Tennant in 1804. See Iridium research below.
