Definitions

  • the invention relates to a material for electrical Contacts consisting of a mixture of silver, a silver alloy or a silver composite material with 0.05 to 7% by weight Carbon that is cold isostatically pressed and sintered.
  • the US-PS 2,319,240 describes a silver-carbon material for electrical contacts, except for graphite other carbon can also be used. About the Type of carbon and the size of this No information is given on carbon particles. The These materials are produced by mixing corresponding powder, pressing the powder into one Semi-finished products and sintering.
  • Carbon blacks with primary particle sizes below 25 nm or between 10 and 100 nm are from DE-PS 23 57 524 and from Font "Electrically conductive plastics", Carl Hauser Verlag, Kunststoff, 1986, pages 55-61.
  • This object is achieved in that the Carbon only in the form of soot with a mean primary particle size of less than 150 nanometers the silver, silver alloy or Silver composite powder is added.
  • the average primary particle size of the is preferably soot used at less than 100 nanometers.
  • soot can also be added Burning behavior of, for example, AgNi and AgCuO composites be improved.
  • the contact pieces produced according to Examples 1 to 3 were tested in a model test bench at 100 A in their Burning behavior and at 1000 A in their welding power with the same composition of silver graphite tools compared, which instead of carbon black graphite powder or Graphite powder and graphite fibers included.
