Cobalt (Co) Nanopowder / Nanoparticles are high-purity metallic cobalt particles with an average size of 100 nm, offering enhanced surface area and reactivity compared to bulk cobalt. In its metallic form, cobalt is hard, solid, and exhibits a distinctive greyish color. It has exceptionally high melting (1495°C) and boiling (2927°C) points, providing thermal stability for advanced applications.
At room temperature and under standard pressure, cobalt is highly resistant to oxidation; however, when heated, it readily forms cobalt oxides, which display a range of colors depending on the oxidation state. These unique chemical and physical properties make cobalt nanoparticles highly valuable in energy storage, magnetic, and catalytic applications.
Applications
Magnetic Materials: Used in high-performance magnets, magnetic recording media, and magnetic fluids due to their strong ferromagnetic properties.
Catalysis: Effective catalyst in Fischer–Tropsch synthesis, hydrogenation, and other industrial chemical reactions.
Electronics: Incorporated into magnetic sensors, spintronics, and microwave-absorbing materials.
Energy Storage: Improves performance in lithium-ion and sodium-ion batteries as an anode/cathode component.
Biomedical Uses: Potential applications in drug delivery, MRI contrast agents, and targeted cancer therapies (research-grade).
Ceramics & Pigments: Forms cobalt oxides with vibrant colors for use in ceramics, glass, and paints.
Handling & Storage:
Cobalt nanopowder should be handled in an inert or controlled atmosphere to prevent unwanted oxidation. Store in sealed, vacuum-packed containers in a cool, dry place away from heat, sparks, and moisture.
