We studied the characteristics of Ni paste used for the fabrication of internal electrodes of multilayer ceramic chip capacitors (MLCC). The effect of addition of BaTiO_3 powders to Ni paste on green density and sintering characteristics of electrode films were also evaluated. Green density of Ni electrode film increased monotonically with an increase in the amount of BaTiO_3 powder up to 10 mass%. From the measurement of shrinkage of electrode films, it was observed that the shrinkage of Ni electrode film prepared from CYD powder was smaller than that of WCP Ni electrode film at the addition of 10 mass%BaTiO_3 powder. The results indicated that properties of Ni powder influenced on the shrinkage of electrode films.
