Patent ID: 7060144

Claim:
A method for manufacturing a ceramic capacitor, comprising the steps of: (a) making unsintered ceramic powder, wherein the unsintered ceramic powder includes a primary component of a perovskite crystal structure in a form of ABO 3 and an additive containing an A-site component of the perovskite crystal structure; (b) forming ceramic green sheets by mixing the unsintered ceramic powder and an organic binder; (c) printing internal electrodes on the ceramic green sheets to provide electrode printed green sheets; (d) laminating the electrode printed green sheets; (e) cutting the laminated ceramic green sheets according to the printed internal electrodes pattern to provide chip-shaped laminated bodies; and (f) sintering the chip-shaped laminated bodies to thereby produce a sintered body including ceramic grains, a ratio A/B of an outer portion of the ceramic grains being greater than that of an inner portion thereof; wherein the unsintered ceramic powder further includes tetraethoxysilane and the additive containing the A-site component is barium acetate.
