Abstract

PURPOSE:To obtain piezoelectric ceramic having high piezoelectric characteristic, etc., by mixing raw materials of a constituting components from which lead oxide or lead oxide plus a part of the constituting components have been removed in a stage of the production of a piezoelectric ceramic having a specified compsn., calcining the mixture, adding lead oxide and insufficient raw material components to the calcined product, mixing the materials, calcining again, molding the calcined product, then calcining finally. CONSTITUTION:In a stage of production of a piezoelectric ceramic expressed by the formula, raw materials for at least two components among the constituting components other than lead oxide are weighed so as to obtain a weight ratio corresponding to a specified proportion of the raw materials, or so as to obtain a part of said specified proportion in the first stage, mixing the materials, and then executing the first calcination. Then, lead oxide and the raw materials insufficient for the specified constitutional ratio are added to the first calcination product. After mixing and pulverization, the second calcination is executed. By calcining further a calcined product obtd. in the above described stage after molding the calcined product, a lead titanate zirconate piezoelectric ceramic is obtd.
