MANUFACTURING METHOD OF DIELECTRIC CERAMIC MATERIAL, GREEN SHEET, SINTERED BODY AND MULTI LAYERED CERAMIC CONDENSER USING DIELECTRIC MATERIAL MANUFACTURED THEREBY

摘要

A method for manufacturing a dielectric ceramic material and a multi-layered ceramic condenser manufactured by the same are provided to secure stable electrical characteristic and stable particle size after sintering. A multi-layered ceramic condenser(1) comprises: a condenser chip body(2) consisting of laminated dielectric layers(3) and inner electrodes(4) in turns; and an outer electrode(5) installed on the surface of the condenser chip body. The inner electrodes are laminated in order for the end part to be exposed to the surface facing against the condenser chip body. The inner electrodes are electrically connected to the outer electrode comprising a predetermined condenser circuit. The dielectric layer is made of sintered bodies of dielectric ceramic materials. The dielectric ceramic materials are obtained by performing a plastic process, grinding process and a plasma process and adding minute minor-component powder to main component powder.
