Nickel Nanoparticles

Nano Scale (nm) Ni

Nickel (Ni) Nanoparticles, nanodots or nanopowder are black spherical high surface area particles. Nanoscale Nickel Particles are typically 10 - 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 50 - 100 nm range with a specific surface area of approximately 5 - 10 m 2 /g. Nano Nickel Particles are also available in passivated and 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 nickel nanocrystals include numerous catalytic functions such as in the anode of solid oxide fuel cells (SOFC) or in the conductive electrolytic layer of proton exchange membrane (PEM) fuel cells, in replacement of platinum. Also, substituting all or a portion of the platinum with nickel nano particles in automotive catalytic converters would significantly reduce their cost 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, biomedical and bioscience properties. Nickel Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Nickel is a Block D, Group 4, Period 4 element. The electronic configuration is [Ar]3d84s2. In its elemental form nickel's CAS number is 7440-02-0. The nickel atom has a radius of 149.pm and it's Van der Waals radius is 163.pm. It is extensively alloyed with iron, chromium, molybdenum, tungsten and other metals produce stainless and other anti-corrosive steel and other corrosion-resistant alloys. It is highly electronically conductive and has many applications as a result. It is the basis of the nickel hydride battery. Most recently, its conductive properties have made it an ideal component for ceramic anode formulations used in oxygen generation and solid oxide fuel cell applications. Catalytic nickel is used to hydrogenate vegetable oils. Nickel additions to glass and ceramic glazes impart a bright green. It is also used in pigments for this purpose.
