Application of nanosecond electron beam for production of silver nanopowders

Abstract

Experiments on the irradiation of silver nitrate solutions in various liquids by the nanosecond electron beam of a URT-0.5 (0.5 MeV, 50 ns, 1 kW) accelerator facilitated the development of technology for producing silver nanopowders. The powder yield and particle size as a function of the irradiation mode has been established. An increase in the adsorbed dose results in an increased powder yield; however, the particle size decreases and the powder agglomeration rate increases. Therefore, the targeted production of silver nanopowders with a mean particle size in the range of 90 ÷ 1100 nm is possible.
