CONDUCTIVE PIGMENT-COATED SURFACES", ABSTRACT Conductive pigment-coated surfaces may be prepared by alloying a nonnoble conductive metal with an oxidizable material admixing the, alloy with an organic vehicle and a binder to form an ink followed by firing the ink in an oxidizing atmosphere containing about 20% by volume of oxygen at a temperature in excess of 1000°F. If so desired a vitre-, ous frit may also be present in the mixture. The resulting ink will possess desirable characteristics such as increased resistivity to oxidation, and increased firing strength when the oxidizable material such as boron is present in the alloy in an amount in the range of from about 12% to about 25% by …
