General description
This copper nanopowder is a fine reddish-brown to black powder made of metallic copper nanoparticles with an average particle size of 25 nm. The particles are not oxidized and we recommend storing the product under inert gas to preserve the unoxidized surfaces.
Application
Copper nanopowder, 25 nm can be used for a variety of applications such as printed electronics, electroless copper plating, heat transfer fluids, catalysis, and thermal energy storage.
