Abstract (en)
[origin: DE19602812C1] The invention concerns the production of a shaped part from a silver-based contact material. According to the invention, a powder mixture is formed from silver and a metal oxide and is processed powder-metallurgically to form the shaped part, the metal oxide being reduced to metal. Since metal oxide powders with a considerably finer grain size than metal powders are available, a contact material of which the metal incorporated as active component has an average grain size of less than 1 mu m can be obtained. Owing to the fine grain size, a contact material of this type has particularly advantageous switching properties.
