Formation of electrode and electronic parts using the same

Abstract

Abstract PURPOSE:To prevent characteristics of electronic parts from being deteriorated in heat diffusion and reduction processes at the time of burning by performing reduction within hydrogen environment after canning a palladium of 5.0-15.0wt.% into an oxidized nickel powder where a copper oxide of 0.1-20.0mol% is added and then performing burning in the air. CONSTITUTION:A copper oxide of 0.1-20.0mol% is added to enhance reduction property of a nickel oxide, a noble metal (palladium) of 5.0-15.0wt.% is canned to prevent mutual reaction with a material to be combined, it is calcined within air, and it is reduced in hydrogen environment. As a result, heat diffusion during calcination of a nickel oxide electrode where copper oxide is added is restricted and then the sintered film can be reduced at low temperature for metallizing, thus preventing electrical characteristics of parts (ceramic capacitor, ferrite, resistor, alumina substrate, multilayer wiring substrate, etc.) for forming an electrode from being damaged and forming the electrode inexpensively.
