Abstract
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to improve the production process of the micro-sized silver powder for thick film silver pastes for applications in the photovoltaic sector and the printed electronics. Relatively high concentrations of the reagents were used to achieve a high yield of silver particles. It was a strict request for highly economic production. This paper shows the possibilities for the routes for future large-scale synthesis and potential industrial production. The particles were analyzed by the X-ray diffraction (XRD), scanning electron microscopy (SEM), and laser diffraction particle size analyzer.
Highlights
Silver is used extensively through history as precious metal value, for coins and art, and in the modern times in numerous industrial and commercial applications
A high concentration of reagents were used, in the aim to get a maximal yield of the silver powder, which is the ultimate requirement from the industry
This study has presented the procedure for the production of micro and sub-micro sized silver particles by chemical reduction method
Summary
Silver is used extensively through history as precious metal value, for coins and art, and in the modern times in numerous industrial and commercial applications. Dimitrijević et al - Production of Sub-Micro Sized Silver Particles by Chemical ... It is the right method for the synthesis of the nanoparticles, but sub-micro sized are difficult to obtain with the narrow size distribution.
