Abstract

PURPOSE:To enable easy mass-production of a dense piezoelectric ceramic having excellent piezoelectric characteristics, at a low cost, by calcining a lead titanate zirconate piezoelectric ceramic in a lead atmosphere in the presence of an oxygen-releasing substance. CONSTITUTION:A lead titanate zirconate piezoelectric ceramic is calcined in a lead atmosphere in the presence of an oxygen-releasing substance. The oxygen- releasing substance is e.g. Pb3O4, Sb2O5, BaO2, Co2O3, Co3O4, MnO2, RbO2 or U3O8. When the amount of the oxygen-releasing substance is too small, the amount of released oxygen is decreased to deter the densification in sintering. When it is excessive, the lead in the atmosphere is absorbed in or reacted with the substance left after the release of the oxygen and the calcining cannot be carried out under prescribed lead vapor pressure. The amount of the oxygen- releasing substance is preferably 0.5-10g, especially 1-3g per 100cc of the inner volume of the setter.
