Electroexploded Metal Nanopowders is a new approach to ultrafine metal powder production that opens up opportunities in materials science and commercial applications. Electroexploded Metal Nanopowders are low-cost, can be made with a broad range of metals, and are up to 500 times smaller than previous commercially available metal powders. Their small size makes their surface area per volume and reactivity far greater than other ultrafine metal powders.

Commercial applications for Electroexploded Metal Nanopowders include catalysis, batteries, microelectronic contacts, lubrication, sintering/welding, coating substrates for wear or corrosion resistance, and more.
