概要

In order to obtain thinner Ni electrode layers for MLCCs, BaTiO_3 organometal resinate was added into Ni paste, which consisted of 0.2μm or 0.4μm Ni powders. Ni electrode films were fabricated with the Ni paste added with BaTiO_3 organometal resinate, and sintering and electrical characteristics of the film were examined in the present study. The experimental results indicated that addition of BaTiO_3 organometal resinate as small as 1 mass% remarkably suppressed the sintering of the Ni electrode films, i.e., no abnormal grain growth was observed on Ni electrode films with BaTiO_3 organometal resinate. In addition, MLCCs with 10-stacked layers was experimentally fabricated. The results indicate that the continuity of electrodes characteristics of the MLCCs are not impaired regardless of the size of the Ni particles. An addition of BaTiO_3 organometal resinate was found to be extremely effective for obtaining thin electrode layers.
