An affordable way to get silver nanoparticles for conductive inks and pastes

Abstract

In this paper, we study the process of obtaining silver nanoparticles by the method of electrospark erosion of silver electrodes in distilled water with a significant overvoltage of the electrode gap. Studies were conducted on the previously developed experimental setup. The results showed that when the air discharge gap FV1 is much larger than the working discharge gap FV2, their exact ratios do not affect the particle size of the nanopowder. The particle size of the nanopowder is determined by other, not yet established process factors. Manufactured nanopowders have the same average size for all production modes and are characterized by a small scatter of particle sizes. The development of the process of obtaining silver nanoparticles by the method of electrospark erosion will reduce the cost of conductive inks and pastes in the future.
