Aluminum (Al) Nanoparticles, nanodots or Nanopowder are black spherical high surface area metal particles. Nanoscale Aluminum Particles are typically 10-30 nanometers (nm) with specific surface area (SSA) in the 30 - 70 m 2 /g range and also available in with an average particle size of 70 -100 nm range with a specific surface area of approximately 5 - 10 m 2 /g. Nano Aluminum Particles are also available in passivated and in Ultra high purity and high purity and carbon 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 aluminum nanocrystals include as a support to create high surface area catalysts, in anti-microbial, anti-biotic and anti-fungal (fungicide) agents when incorporated in coatings, plastics and textiles, and in super strong metals and alloys, such as nano-crystalline aluminium alloys for space applications as alternatives for titanium in components of liquid rocket engines (e.g. lines and turbopumps), since they are lighter and less susceptible to embrittlement by hydrogen, and in nanowire, nanofiber and and in certain other alloy and catalyst applications. Further research is being done for their potential electrical, dielectric, magnetic, optical, imaging, catalytic, biomedical and bioscience properties. Aluminum Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
Aluminum is a Block P, Group 13, Period 3 element. The electronic configuration is [Ne] 3s2 3p1. In its elemental form aluminum's CAS number is 7429-90-5. The aluminum atom has a radius of 143.2.pm and it's Van der Waals radius is 200.pm. Aluminum is a silvery-white metal that possesses many desirable characteristics. It is light, nonmagnetic and nonsparking. It stands second among metals in the scale of malleability, and sixth in ductility. It is extensively used in many industrial applications where a strong, light, easily constructed material is needed. Although it's electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. |
