Abstract
The purpose of this invention is to provide a terminal electrode composition for a multiple-layered capacitor that is suitable for a plating base and that has improved resistance to heat stress as the result of sintering at a low temperature (high reliability). The terminal electrode composition for multiple-layered capacitor of this invention is made of precious metal particles and 0.5-7 wt. % (based on the weight-of the precious metal particles) of an inorganic binder having a 400.degree.-500.degree. C. glass transition point and a 400.degree.-550.degree. C. glass softening point.
Claims4
A terminal electrode composition for a multiple-layered capacitor, characterized by being made of precious metal particles and 0.5 to 7 wt. % (based on the weight of the precious metal particles) of an inorganic binder having a 400.degree.-500.degree. C. glass transition point and a 400.degree.-550.degree. C. glass softening point, wherein said inorganic binder comprises 15-30 wt. % SiO.sub.2, 1-18 wt. % B.sub.2 O.sub.3, 35-70 wt. % PbO and 5-20 wt. % of at least one oxide selected from the group consisting of Al.sub.2 O.sub.3, ZrO.sub.2 and TiO.sub.2.
