Ossila M2444A1 is a silver nanopowder (Ag, CAS 7440-22-4) made up of spherical particles with an average size of 20 nm and a purity of ≥ 99.95%. It appears as a grey powder and is offered in 5 g, 10 g and 25 g packs.
Silver is valued for its very high electrical conductivity, which is why silver nanoparticles are a common ingredient in conductive pastes for electronic devices and printed electronics. They also act as antimicrobial agents, as they interact with phosphate-containing compounds inside cells and with sulfur-containing proteins in cell membranes.
Energy research is a growing area of use. In published work, a zinc-air battery with an air cathode based on silver and graphene oxide reached a maximum current density of 150 mA/cm2 at 0.44 V, and a silver powder-modified graphite-composite anode interlayer gave homogeneous Li10Ag3 formation with minimal Li residue after discharge. Adding silver nanopowder to an N719 dye-sensitized solar cell raised its efficiency from 0.98% to 1.2%.
