ABSTRACT:
A piezoelectric ceramic composition which comprises the combination of a pyrochlore composite oxide and a base ceramic mixture of PbTiO.sub.3 and PbZrO.sub.3 is prepared by individually forming pyrochlore composite oxide, PbTiO.sub.3 and PbZrO.sub.3 components; and sintering a mixture of the formed components at a temperature greater than 1,000.degree. C.
