Chromium Oxide (CrO) Nanoparticles, nanodots or Nanopowder are white spherical high surface area metal particles. Nanoscale Chromium Oxide Particles are typically 10-30 nanometers (nm) with specific surface area (SSA) in the 130-150 m 2 /g range. Nano Chromium Oxide 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 Chromium Oxide nanocrystals include for their magnetic properties, as a Magnetic Nanoparticle with numerous uses, in microbatteries, and nanowire, and in certain alloy and catalyst applications . Chromium Oxide Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Chromium is a Block D, Group 6, Period 4 element. The electronic configuration is [Ar] 3d⁵ 4s¹. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green.
