    摘要: A multi-layer capacitor includes a plurality of dielectric layers, a pair of external electrodes and a multiplicity of internal electrode layers, each internal electrode layer being interposed between every two neighboring dielectric layers. Said two neighboring internal electrode layers and the dielectric layer disposed therebetween form a unit capacitor so that the multiplicity of internal electrode layers and the dielectric layers therebetween constitute a stack of three or more vertically stacked unit capacitors. The electrostatic capacitance of the unit capacitor located at a center of the stack is greater than those of the unit capacitors located at an is upper end and a lower end of the stack.

    摘要: The process for preparing ceramic powder having a core-shell structure by dissolving a crystalline ceramic powder In water so as to leave a core portion of the ceramic powder while heating; depositing a component of the ceramic powder dissolved in the water on and around surfaces of the core portion thereof as a deposited material from the water by gradually cooling the ceramic powder and the water obtained in the step of dissolving; and firing a mixture of the ceramic powder obtained in the step of depositing with an additive at a high temperature to subject the deposited material and the additive to solid phase reaction to form a shell portion on and around the core portion of the ceramic powder. The process can produce the ceramic powder having a core-shell structure from a crystalline ceramic powder, thereby achieving high electrical and mechanical features when formed into ceramic electronic parts. On the other hand, conventional ceramic electronic parts produced from highly crystalline ceramic powder raise the manufacturing cost because such ceramic powder is low in reactivity so that it requires high firing temperature. Ceramic powder in a core-shell structure produced from low-crystalline ceramic powder results to conventional ceramic electronic parts which are poor in electrical and mechanical characteristics.
