Low temperature sintered ceramic capacitor with a temperature compensating capability, and method of manufacture
A low temperature sintered solid dielectric capacitor is described comprising a dielectric ceramic body and at least two electrodes in contact therewith. The dielectric ceramic body consists essentially of: 100 parts by weight of a major ingredient expressed by the formula, (SrO)/sub k/ . (Zr/sub 1-x/Ti/sub x/)O/sub 2/, where k is a numeral in the range of 0.8 to 1.3 inclusive; and x is a numeral in the range of zero to 0.25 inclusive; and from 0.2 to 10.0 parts by weight of an additive mixture of boric oxide, silicon dioxide and at least one metal oxide selected from the group consisting of barium oxide, magnesium oxide, zinc oxide, strontium oxide and calcium oxide, the relative proportions of boric oxide, silicon dioxide and at least one selected metal oxide constituting the additive mixture attached hereto which is bounded by the lines sequentially connecting: the point A where the additive mixture consists of 15 mole percent boric oxide, 25 mole percent silicon dioxide, and 60 mole percent metal oxide; the point N where the additive mixture consists of 30 mole percent boric oxide, zero mole percent silicon dioxide, and 70 mole percent metal oxide; the point C where the additive mixture consists of 90 mole percent boric oxide, zero mole percent silicon dioxide, and 10 mole percent metal oxide; the point D where the additive mixture consists of 90 mole percent boric oxide, 10 mole percent silicon dioxide, and zero mole percent metal oxide; and the point E where the additive mixture consists of 25 mole percent boric oxide, 75 mole percent silicon dioxide, and zero mole percent metal oxide.
