PROBLEM TO BE SOLVED: To produce a dielectric porcelain composition capable of densifying it at a low burning temp. and also having good electrical characteristics. SOLUTION: 0.003-0.035pt.mol. Bi (expressed in terms of Bi2 O3 ), 0.0005-0.0050pt. mol. Mn (expressed in terms of MnO2 ) and 0.002-0.040pt.mol. Ag (expressed in terms of Ag2 O) are incorporated in a fundamental composition expressed by the formula, (Ba1-x Znx )O.n(Ti1-y Siy )O2 (where 0.05<=x<=0.25, 0.01<=y<=0.15, 3<=n<=6) based on 1 mol of the fundamental composition. |
