Abstract:
1. A method for manufacturing a laminated ceramic capacitor, comprising: (a) providing an ultrafine nickel powder made by subjecting nickel chloride to a vapor phase hydrogen-reducing process in the presence of supplied sulfur to form said ultrafine nickel powder having a sulfur content of 0.02 to 1.0 wt % and an average particle size of 0.1 to 1.0 μm; (b) printing a paste of the ultrafine nickel powder to form an internal electrode layer on a first ceramic dielectric sheet layer; (c) stacking a second ceramic dielectric sheet layer on the printed internal electrode layer; (d) repeating steps (b) and (c) at least one time to form a multilayer body; (e) pressing the multilayer body; and (f) cutting and sintering the multilayer body.
