Attorney, Agent or FirmInternational ClassH01G 4/12 (20060101)AbstractAn improved high dielectric constant ink useful in making thick film capacitors is disclosed in which a dielectric material is combined with a glass bonding agent having at least one electropositive element therein which is common with the powdered, high dielectric material which is one selected from the group consisting of chemically pure barium titanate and chemically pure barium titanate modified with from about 0.125% to about 5.0% by weight of a metal oxide additive. The glass bonding agent is an alkali-free binder comprising from 3 percent to 7 percent by total weight of the dielectric and binder materials. | |
