In order to obtain thinner Ni electrode layers for MLCCs, BaTiO3 organometal resinate was added into Ni paste which consisted of 100nm Ni powders. Ni electrode films were fabricated with the Ni paste added with BaTiO3 organometal resinate, and sintering and electrical characteristics of the film were examined in the present study. The experimental results indicated that addition of BaTiO3 organometal resinate remarkably suppressed the sintering of the Ni electrode films, i.e., no abnormal grain growth was observed on Ni electrode films with BaTiO3 organometal resinate. In addition, MLCCs with 10stacked layers was experimentally fabricated. And the capacitance, the dielectric loss and insulating resistance of MLCCs were measured. The results indicate that even when the of BaTiO3 organometal resinate added is, the electrical characteristics of the MLCCs are not impaired regardless of the nano-size of the Ni particles. An addition of BaTiO3 organometal resinate was found to be extremely effective for obtaining thin electrode layers.
