Abstract
Abstract In compositions of noble metal(s) dispersed in an inert vehicle which are useful for forming electrodes on dielectric substrates, improved electrode compositions comprising an amount of NiO effective to increase fired conductor adhesion to substrates; since the resultant fired electrodes have increased adhesion to ceramic dielectric substrates, they have special utility in forming surface metallizations in electronic circuits.
