Abstract of the Disclosure

A conductive metallizing composition adapted to be deposited and fired at 725-900 degrees Celsius on an insulating substrate to forma conductive element thereon comprises: a metal component comprising 60-70 percent gold, 10-20 percent platinum and 10-30 percent palladium; a vitreous frit component; and, a vehicle

  • Figure 1 is a flow diagram illustrating the materials used and the operations performed in fabricating a conductive element using the novel metallizing composition of the present invention.
  • Figure 2 is a fragmentary perspective view of a pattern of conductive elements on a ceramic substrate.
  • Figure 3 is a cross-sectional illustration of the crossover of two conductive elements such as shown in Figure 2.
  • Figure 4 is a plot of percentages, by weight, of vitreous frit or flux in the composition vs. adhesion.
