A gold-plated metal powder is used to provide a low resistance (highly conductive) paste for use in electroplating gold or nickel on ceramic substrates. The present conductive pastes have as metal powders either silver or nickel or COBALOY* loaded into various vehicles which provide screenability and other processing criteria. Silver loaded pastes leave silver residues which cause migration and harm the functional values of the substrate. Nickel loaded pastes are affected by oxidation and become resistant to some degree so as to adversely affect plating uniformity.
