摘要： A low temperature fired ceramic dielectric composition in which the dielectric constant does not vary from its base value of over 2400 by more than 15 percent over a wide temperature range. A base ceramic preparation (a) and a ceramic flux (b), each consisting essentially of metal oxides or precursors thereof to provide in oxide form (a) 98.0 to 99 weight percent barium titanate, from about 0.97 to about 1.54 weight percent niobium pentoxide and from about 0.19 to about 0.32 weight percent cobalt oxide; (b) from about 16 to about 60 weight percent bismuth titanate, about 8 to about 52 weight percent lead titanate, about 18 to about 35 weight percent zinc oxide and about 5 to about 11 weight percent boron oxide. Manganese dioxide or precursor thereof in amount of from about 0 to 0.114 percent of the combined weight of the base ceramic preparation and ceramic flux is added to the metal oxides or precursors of the base ceramic preparation and ceramic flux and the mixture is fired at a temperature less than about 1150.degree.

摘要： A multi-layer ceramic capacitor is characterized by a ceramic composition including barium titanate and lithium fluoride as essential ingredients resulting in the capability of sintering the composition at temperatures below 1100.degree. C. As a consequence, the electrodes for the capacitor can be formulated from pure silver or a silver palladium composition in which the major component is silver thereby decreasing the expense of such capacitors as compared to those requiring platinum, gold, or mixtures of these precious metals and/or similar precious metals in making up the electrodes.
