Using Nanosecond Electron Beam to Produce Silver Nanopowder

Abstract

Experiments with a URT-0.5 accelerator (0.5 MeV, 50 ns, 1 kW) generating a nanosecond electron beam for irradiation of silver nitrate in various liquid solutions (water and toluene) were performed with the aim of producing silver nanopowders. A radiochemical reaction allows making weakly agglomerated pure Ag powders with particles of 10-15 nm and 30-50 nm in size by irradiation in toluene and water respectively. The injection of the nanosecond electron beam energy to the solution is optimal. As the absorbed dose increases, the output of the radiochemical reaction does not grow, but more agglomerated powders are synthesized.

Application of nanosecond electron beam for production of silver nanopowders

“…During the irradiation of the solution in toluene [19], weakly agglomerated silver powders with particle sizes of 3−5 nm were produced (Fig. 4).…”
