Abstract: The invention relates to a conductive paste containing a glass frit, a paste-forming medium, conductive particles made of silver and particles containing non-precious metal, in order to produce a conductive coating on glass, ceramics or enameled steel, a method for producing said coating and articles coated therewith. According to the invention, the conductive particles containing non-precious metal correspond to up to 80 wt. % of all conductive particles, and are essentially made up of iron, cobalt, nickel, copper, zinc or an alloy containing at least one of these elements, especially nickel, and have an average particle size d50 ranging from 0.1-15 &mgr;m and a specific surface ranging from 0.5-10 m2/g. The glass frits begin to soften at 350° C.-600° C. and have a hemisphere temperature of 450° C.-700° C.

Abstract: The invention relates to a process for producing a conductive coating on glass and enamelled steel using a screen-printable aluminum paste. The paste to be used contains: 40 to 80 wt. %, in particular, 50 to 75 wt. % aluminum powder; 5 to 40 wt. %, in particular, 9 to 25 wt. % glass frit having an initial softening temperature of 400 to 700° C., in particular, 420 to 580° C.; 10 to 35 wt. % of a liquid or thermoplastic medium; and 0 to 10 wt. % sintering aid. The substrate coated with the paste is heated at 500 to 750° C., in particular, 590 to 690° C. The coating on the substrate is characterized by having a low specific resistance of less than 100 &mgr;ohm·cm, in particular in the range of 10 to 70 &mgr;ohm·cm, and good adhesion.
