Abstract

PURPOSE:To increase the coefft. of electromechanical coupling of a Pb-Ni-Nb-Ti- Zr-O type piezoelectric porcelain compsn. in the diametral direction and the dielectric constant and to make the compsn. suitable for use as a sound transducing element, etc., by incorporating a specified amt. of La2O3, Sb2O5 or CeO2 as a subsidiary component into the compsn. CONSTITUTION:Starting materials such as PbO, NiO, Nb2O5, TiO2 and ZrO2 are weighed so as to obtain a piezoelectric porcelain compsn. represented by the formula and they are mixed and calcined. La2O3, Sb2O5 or CeO2 as a subsidiary component is added to the resulting compsn. represented by the formula as a principal component by 0.1-0.3wt.% and they are mixed, molded and calcined to obtain a desired piezoelectric porcelain compsn. Since the subsidiary component has been added, the compsn. has such characteristics as >=0.55 coefft. of electromechanical coupling in the diametral direction and >=2,000 dielectric constant and is suitable for use as a sound transducing element.
