Preparation method for multilayer ceramic capacitor

The invention discloses a preparation method for a multilayer ceramic capacitor. The preparation method comprises the following steps of preparing ceramic thin films and ceramic thin films on which inner electrode patterns are printed, wherein a plurality of ceramic thin films on which the inner electrode patterns are printed are laminated to obtain a laminating unit; respectively laminating a plurality of ceramic thin films on two opposite side faces of the laminating unit, and pressing in and cutting the ceramic thin films to obtain laminating bodies; laminating, pressing in and cutting the plurality of ceramic thin films to obtain green blocks; placing the laminating bodies and the green blocks on a load bearing board, wherein the laminating bodies are placed in a middle area, and the green blocks encircle the peripheries of the laminating bodies, and performing agglomeration discharging and sintering on the laminating bodies to obtain a ceramic body; after chamfering the ceramic body, attaching two outer electrodes at two ends of the ceramic body. According to the preparation method for the multilayer ceramic capacitor, during sintering, sintering-aid components in the green blocks volatilize, so that local atmosphere with higher volatile concentration is formed at the peripheries of the green bodies, and the ceramic body obtained by sintering is uniform, dense and good in consistency.
