Zn-Cu electrodes were composed on both surfaces of ceramic capacitors and their characteristic properties were investigated. An oxidation ratio of the fired Zn electrodes was examined by a chemical analysis or an XPS. It was found that Zn metals are oxidized at the ratio of ca. 50%. The electrical properties of a BaTiO3-based ceramic capacitor (Y5V) with a Zn-Cu electrodes were equal to those with a silver electrode. As a result of migration tests examined in distilled water, the reaction started after holding for 1 min. in a fired silver electrode, and for 9 min. in Cu plating and Zn-Cu electrodes, but no reaction occurred even more than 15 min. in a fired Zn electrode.
