To this major ingredient is added a minor proportion of a mixture of lithium oxide, silicon dioxide, and one or more metal oxides selected from among barium oxide, magnesium oxide, zinc oxide, strontium oxide and calcium oxide. For the fabrication of capacitors the mixture of the above major ingredient and additives in finely divided form are formed into moldings of desired shape and size, each with at least two electrodes buried therein. The moldings and electrodes are cosintered in a reductive or neutral atmosphere and then are reheated at a lower temperature in an oxidative atmosphere. the cosintering temperature can be so low that nickel or like base metal can be employed as the electrode material.

Abstract: A monolithic ceramic capacitor having a higher DC breakdown voltage per unit thickness of the dielectric ceramic body than heretofore. The major ingredient of the ceramic is expressed as {(Ba.sub.1-x-y Ca.sub.x Sr.sub.y)O}.sub.k (Ti.sub.1-z Zr.sub.z)O.sub.2, where x, y, z and k are numerals in the ranges specified herein. To this major ingredient is added a minor proportion of a mixture of boric oxide and silicon dioxide in specified ranges of proportions. For the fabrication of capacitors having dielectric bodies of the above composition, the moldings of the mixture of the major ingredient and additives in the specified proportions are sintered to maturity in a reductive or neutral atmosphere and then reheated at a lower temperature in an oxidative atmosphere. The sintering temperature can be so low (1000.degree.-1200.degree. C.) that the moldings can be cosintered with base metal electrodes buried therein.
