  • Ceramic capacitor and manufacturing method thereof
    Patent number: 4942496
    Abstract: A ceramic capacitor comprising a dielectric ceramic element made of materials a metal oxide as the principal ingredient. On the surface of the dielectric ceramic element are formed a plurality of electrodes. The materials used for the electrode are selected such that their principal ingredients have a stronger oxidizing tendency than those used for the dielectric ceramic element. The electrode is formed by applying this electrode material on the surface of the dielectric ceramic element and subsequently baking in a non-reducing atmosphere. This process reduces the surface of the dielectric ceramic element underneath the electrode and a reduced layer is thus formed.
