Description
Cobalt (Co) Nanopowder / Nanoparticles – 99.8% Purity, 28 nm, Carbon Coated, Metal Basis
Cobalt (Co) Nanopowder / Nanoparticles are ultra-fine spherical particles with an average particle size (APS) of 28 nm and a high purity of 99.8% (metal basis). Produced via laser evaporation technology, these nanoparticles are carbon coated (C = 4.28 wt%) to enhance stability, prevent oxidation, and maintain excellent dispersibility.
The carbon coating layer provides additional protection against agglomeration and environmental degradation, making these nanoparticles ideal for high-performance applications in magnetic materials, energy storage, EMI shielding, and biomedical technologies.
With a specific surface area of 40–60 m²/g and a bulk density of 0.08–0.20 g/cm³, Cobalt Nanoparticles offer exceptional electromagnetic and catalytic properties, opening a wide range of advanced scientific and industrial uses.
