Method for manufacturing piezoelectric ceramic, piezoelectric ceramic, and piezoelectric element
A method for manufacturing a piezoelectric ceramic, comprising a step for preparing a raw material to include A, B, Ba, and Zr in the composition ratio represented by the general formula (1-s)ABO3-sBaZrO3 (where A is at least one species of element selected form alkali metals, B is at least one species of transition metal element including Nb, and s ranges from 0.06 to 0.15 but can also be equal to 0.15), a step for molding the raw material to obtain a molded article, a step for firing the molded article in a reducing atmosphere, and a step for heat treating, in an oxidizing atmosphere, the fired body obtained by the firing step.
