ABSTRACT:
A contact material, a shaped article or contact piece and a process for producing a shaped article from a contact material based on silver, include forming a powder mixture from silver and a metal oxide, and metallurgically processing the powder to form the shaped article with the metal oxide being reduced to metal. Since metal oxide powders are obtainable with a very much smaller particle size than metal powders, it is possible to obtain a contact material with a mean particle size of the metal incorporated as an active component of less than 1 .mu.m. Such a contact material has particularly favorable switching properties as a result of the fine particle size.
