Title:
CONDUCTING PASTE FOR TERMINAL AND LAMINATED CERAMIC CAPACITOR
Document Type and Number:
Japanese Patent JPH11243029
Kind Code:
A
Abstract:

To improve the wettability of base metal and glass and to improve the minuteness of an outer terminal, by including at least one kind of nitrate salt of alkaline earth metal into conducting paste for a terminal comprising base metal powder, glass frit and organic vehicle.

At both end parts of the main body of a capacitor which is formed by alternately laminating an inner electrode layer comprising base metal and a dielectric layer, an outer terminal comprising the base metal and the sintered body is formed. Glass phase 7 is dispersed in the outer terminal, and 30-50 volume % is present in the outer terminal. This conducting paste is for the terminal and is composed of base metal powder 8, a glass frit and organic vehicle. By containing at least one kind among, e.g. Ba(NO3)2, Sr(NO3)2 and Ca(NO3)2, oxygen is discharged at the time of baking the outer terminal. An oxide film is formed for Cu powder. The wettability with the glass frit is improved, and the minuteness of the outer terminal can be improved.
