Abstract (en)
[origin: US4980125A] Sinter materials having the constitution AgSnO2Bi2O3CuO produced from an intraoxidized alloy powder have added thereto bismuth zirconate and/or bismuth titanate in parts by weight of preferably between 0.1 and 5%. For the production of these materials, bismuth zirconate and/or bismuth titanate is added as a separate powder to the intraoxidized alloy powder of AgSnO2Bi2O3CuO. With such a contact material, the excess temperature behavior in motor contactors is significantly improved.
