Sinter materials having the constitution AgSnO.sub.2 Bi.sub.2 O.sub.3 CuO 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 AgSnO.sub.2 Bi.sub.2 O.sub.3 CuO. With such a contact material, the excess temperature behavior in motor contactors is significantly improved.

Sinter contact material for low voltage switching apparatus of the

The invention relates to a method for the production of a filled layer component made out of a monolithic ceramic body by impregnating a ceramic layer body of dense and porous layers with liquid impregnating material which wets the ceramic and by applying contacts. According to the invention the contacts are applied following the impregnation process without any further intermediate steps, and an electrical bonding of the contacts to the metal filler takes place.
