  • Patent number: 10312020
    Abstract: In an embodiment, a multilayer ceramic capacitor 10 has a first external electrode 12 and a second external electrode 13 that each contain metal grains MP and dielectric grains DP, where an oxide of the same metal element constituting the metal grain MP, or MO, is present at the interface between the metal grain MP and the dielectric grain DP. The multilayer ceramic capacitor can prevent the hardness of its external electrodes from dropping, even when the external electrodes contain metal grains and dielectric grains.

  • Patent number: 7495883
    Abstract: A multilayer ceramic capacitor and a method of manufacturing the same is provided. The capacitor comprises dielectric layers and internal electrode layers alternately stacked. Two of the internal electrode layers that are located outermost and/or at least one of the internal electrode layers that is located inside each outermost internal electrode layer are substantially oxidized and do not function as electrodes. The capacitance of the multilayer ceramic capacitor depends on the unoxidized internal electrode layers other tan the oxidized ones. The method of manufacturing a multilayer ceramic capacitor comprises forming green dielectric layers, forming green internal electrode layers, preparing a green ceramic chip, forming green external electrodes, and firing the green ceramic chip.

  • Publication number: 20060208575
    Abstract: Diffusion-phase grain layer formed of diffusion-phase grains (first grains G1 and second grains G2) arranged in the form of a layer is present between a dielectric layer and an internal electrode layer. Thus, even if oxygen vacancies formed in third grains G3 constituting the dielectric layer move toward the interface between the dielectric layer and the internal electrode layer to accumulate in the third grains G3 present in the vicinity of the interface, the presence of the diffusion-phase grain layer prevents a current from concentrating in a portion having a reduced resistance due to the oxygen vacancies to suppress insulation degradation that can be formed in the multilayer ceramic capacitor.
