Piezoelectric ceramic, piezoelectric ceramic component, and piezoelectric device using such piezoelectric ceramic component
In a piezoelectric ceramic which has an alkali-containing niobate-based perovskite structure in which constituent elements are Li, Na, K, Nb, and O, a Li3NbO4 crystal phase is intentionally deposited on a piezoelectric ceramic having an alkali-containing niobate-based perovskite structure, whereby sintering becomes possible at about 1000° C. rather than at the normally required sintering temperature of 1050° C. or greater.
