The present invention relates to a method for producing piezoelectric ceramics, which forms a mixed powder of a main component, stirs the mixed powder together with an aqueous solution of (COOH) 2, and adds an aqueous solution of Pb (NO 3) 2 to the stirred powder. The PZT powder was added dropwise to form a PZT powder by the firing step and the sintering step, whereby a small grain size and a dense granule can be obtained. |
