Iridium Nanoparticles

Nano Scale (nm) Ir

Iridium (Ir) Nanoparticles, nanodots or nanopowder are black spherical high surface area metal particles. Nanoscale Iridium Particles are typically 20 - 100 nanometers (nm) with specific surface area (SSA) in the 1 - 5 m 2 /g range. Nano Iridium Particles are also available in Ultra high purity and high purity and coated and dispersed forms. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil. Applications for Iridium nanocrystals include numerous uses in catalysts, electrocatalysts, chemical synthesis, biphasic catalysis and hydrogenation reactions , and as a Magnetic Nanopowder, in polymer membranes to create Active Polymer Membranes and in other coatings, plastics, nanofiber and textiles and in nanowire and other catalysis applications. Additional technical, research and safety (MSDS) information is available.

Iridium is a Block D, Group 9, Period 6 element. The 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 it's Van der Waals radius is 200.pm. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known. It will not react with any acid and can only be attacked by certain molten salts, such as molten sodium chloride. It is alloyed with platinum to produce highly corrosive resistant electrical contacts for spark plugs.
