Effect of Amount of Added BaTiO₃ Powders on Sintering Properties and Electrical Properties of Ni Electrode Films

Abstract

The dispensability of BaTiO₃ powder in Ni paste for multilayer ceramic capacitors and the effect of amount of added BaTiO₃ on the properties of Ni Electrode were studied. Maximum green density of Ni paste film dried at 100°C was obtained when the amount of added BaTiO₃ was 15 mass%.
With addition of BaTiO₃ powder, the shrinkage of Ni electrode decrease and the electrical resistivity of Ni electrode increased. The amount of added BaTiO₃ powder should be less than 30 mass%, because the electrical resistivity increased abruptly when amount of the powder was over 30 mass%.
