Abstract
The process for making silver powder particles with very small size crystallites uses a combination of gum arabic and maleic acid with the reduction of a silver salt with ascorbic acid. Silver thick film paste containing these silver powder particles can be used in electronic applications to form electrodes for semiconductor devices and, in particular, solar cells.
