Abstract
A conductive paste for forming terminal electrodes of a monolithic ceramic electronic component having nickel internal electrodes is provided. The conductive paste includes at least one of a silver powder and a silver alloy powder, a boron powder, an inorganic binder and an organic vehicle. The amount of the boron powder is at least about 0.5 percent by weight and less than about 7.0 percent by weight of the total weight of the conductive paste.
Claims17
A monolithic ceramic electronic component made by the method comprising:
- providing a sintered compact having internal conductor layers comprising nickel and having on an external face in electrical contact with internal conductor layers, a conductive paste comprising at least one of a silver powder and a silver alloy powder;
- a boron powder in an amount of at least about 0.5 percent by weight and less than about 7.0 percent by weight of the total weight of the conductive paste;
- an inorganic binder;
- and an organic vehicle;
- and
- baking the conductive paste to form terminal electrodes electrically connected to the internal conductor layers of the sintered compact.
A monolithic ceramic electronic component comprising a sintered compact of a plurality of ceramic layers having therein an internal conductor layer comprising nickel and having on an external face a terminal electrode comprising silver and boron in electrical contact with the internal conductor layer, wherein at least of portion of the nickel and silver are in solid solution.
