摘要： A multilayer ceramic electronic component includes a laminate having ceramic layers and internal electrodes stacked alternately one on another, and at least one kind of metal oxide between respective one of the ceramic layers and corresponding one of the internal electrodes. A method of manufacturing a multilayer ceramic electronic component includes a first step of stacking ceramic sheets and metal layers alternately one on another to fabricate a laminate and a second step of firing the laminate. Respective one of the metal layers has, on the surface of a sheet-like first metal, a second metal more susceptible to oxidation than the first metal. The second step is performed at an oxygen partial pressure at which the first metal is hardly oxidized and the second metal is oxidized.

摘要： Method for manufacturing a ceramic electronic component such as a voltage-dependent non-linear resistor element and a semiconductive ceramic capacitor is disclosed, in which a precisely uniform metal coating is formed on a surface of a ceramic and the metal coating is then heat treated to convert the metal of the metal coating to a metal compound to form a metal compound coating on the surface of the ceramic and/or diffuse a portion of or all of the metal coating into the ceramic, for attaining completely different electric properties than those of untreated ceramic. The present method is particularly useful in the application to a semiconductive ceramic capacitor.

摘要： A method of manufacturing ceramic includes a first step of compressing a ceramic sheet (10a) containing ceramic powder and organic to reduce porosity, a second step of forming a conductor layer (2) of metallic paste on the ceramic sheet (10b), a third step of stacking a plurality of ceramic sheets (10b) into a laminate such that each ceramic sheet (10b) is sandwiched between conductor layers (2), and a fourth step of sintering the laminate. Since the conductor layer (2) is formed on the ceramic sheet (10b) with its porosity reduced, metallic components are hindered from passing into the ceramic sheet (10b). The conductor layer can be formed by transferring onto a ceramic sheet to suppress the diffusion of the metallic components of the conductor layer. This method reduces short circuits of ceramic devices and increases the yield rate.

摘要： A solid electrolytic capacitor is obtained in which a sintered metal serves as an anode and a silver layer serves as a cathode. A surface of sintered metal made of tantalum or the like and having an open porosity ratio of more than 75% is oxidized so that an oxide film made of tantalum pentoxide or the like is deposited thereon. Cavities of the metal are filled with an electrically conductive material. Then, the metal is wound around a lead wire and made into a desired shape and size. The silver layer is formed on this porous metal body. Because a specific surface area of the sintered metal is large, a large capacity is obtained.
