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

Cobalt is a Block D, Group 9, Period 4 element. The electronic configuration is [Ar] 3d⁷ 4s². In its elemental form cobalt's CAS number is 7440-48-4. The cobalt atom has a radius of 125.3.pm and it's Van der Waals radius is 200.pm. Cobalt has a metallic permeability two thirds that of iron. It exists as a mixture of two allotropes over a wide temperature range. The transformation is slow and accounts in part for the wide variation in the physical properties of cobalt.
