ABSTRACT:
A novel silver powder composition characterized by a very low fusion, or film-forming temperature, probably assignable to the relatively small amount of oxides or other undesirable occlusions within coatings formed of the powder. The invention also relates to a new process for forming such a powder; the process is believed to involve the formation of fatty-acid silver reaction product of the surface of the silver powder before it is subjected to fusion into a metallic coating. During fusion the decomposing reactant seems to act as a flux aiding the formation of a metal film of superior appearance and strength.
