PIEZOELECTRIC CERAMIC, METHOD FOR PRODUCING PIEZOELECTRIC CERAMIC, AND PIEZOELECTRIC CERAMIC ELECTRONIC COMPONENT
A piezoelectric ceramic that contains an alkali niobate compound as its main ingredient. The alkali niobate compound has a perovskite crystal structure represented by AmBO3 and contains an alkali metal. There exists Sn in part of site A, and Zr in part of site B. A radial distribution function obtained from a K-edge X-ray absorption spectrum of Sn has a first peak intensity P1 at a first distance from a Sn atom and a second peak intensity P2 at a second distance from the Sn atom. The second distance is greater than the first distance, and the peak intensity ratio P1/P2 is 2.7 or less.
