Aluminum (Al) Nanoparticles 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 m2/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 m2/g. Nano Aluminum Particles are also available in passivated and in ultra high purity and high purity, carbon-coated, and dispersed forms. They are also available as a dispersion 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.
