Abstract:
1. A method for making a silver-containing film, the method comprising the steps of: applying a layer of paste to a substrate, said paste including particles dispersed in a carrier liquid, said particles including a metallic phase with greater than about 30 weight percent silver; removing said carrier liquid from said layer of paste and forming on said substrate a densified layer including silver from said particles; wherein, said particles being substantially spheroidal, having a weight average size of from about 0.1 micron to about 4 microns, having a size distribution such that at least about 90 weight percent of said particles are smaller than about twice said weight average size and having a mean crystallite size of larger than about 50 nanometers.
