Abstract
The subject of the present invention is to provide a method for producing a piezoelectric ceramic and a piezoelectric element where their burning temperatures can be sufficiently lowered without adding an additive or the like, a method for lowering burning temperature at a burning step in piezoelectric ceramic production and the piezoelectric element which can be obtained by the methods. The method for producing the piezoelectric ceramic comprises a mixing step to prepare a powdery raw material mixture mixed with a raw material containing Pb, Zr and Ti and a burning step to burn the raw material mixture. The raw material mixture satisfying the following equations denoted as D50 ≤ 0.6 μm (1) and D90-D10 ≤ 0.4 μm (2) (wherein, D50 is a mean particle diameter; D90 is a 90% cumulating particle diameter; D10 is a 10% cumulating particle diameter) is prepared at the mixing step.
