Title:
PRODUCTION OF CERAMIC ELECTRICAL COMPONENT
Document Type and Number:
Japanese Patent JP3075230
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide ceramic electrical components having no structural defect or deterioration of electrical characteristics by removing almost all residual organic elements, without oxidizing inner electrodes than extreme degree.
SOLUTION: A ceramic sheet as a ceramic dielectric layer 1 is formed of a ceramic material and polyethylene, and an inner electrode 2 and the sheet are laminated alternately to form a laminate. Next, while the laminated body is kept in an atmosphere where a temperature is higher than dissolving temperature of polyethylene and oxygen concentration is 100 ppm or lower, polyethylene in the laminate is removed. Then after the laminate has been baked at an equilibrium oxygen partial pressure or lower of the inner electrode 2 so as to obtain a sintered body, an outer electrode 3 is formed.
