Iron Nanoparticles

Nano Scale (nm) Fe

Iron (Fe) Nanoparticles, nanodots or nanopowder are spherical or faceted high surface area metal nanostructure particles. Nanoscale Iron Particles are typically 20-40 nanometers (nm) with specific surface area (SSA) in the 30 - 50 m 2 /g range and also available in with an average particle size of 100 nm range with a specific surface area of approximately 7 m 2 /g. Nano Iron 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 Iron Nanocrystals include in environmental clean up of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in coatings, plastics, nanowire, nanofiber and textiles and in certain alloy and catalyst applications. Further research is being done for their potential electrical, dielectric, magnetic, optical, imaging, catalytic, biomedical and bioscience properties. Iron Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Iron is a Block D, Group 8, Period 4 element. The electronic configuration is [Ar] 3d⁶ 4s². In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pm and it's Van der Waals radius is 200.pm. Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Recent applications for Iron nanoparticles include in water treatment of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in certain alloy and catalyst applications. Iron can also be introduced into processes using iron foil, pellets, rod and wire by thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Iron 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. Iron was first discovered by Early Man.
