AbstractThis work investigated the effect of MnO2 addition on the phase structure, microstructure, and electrical properties of AgSbO3-modified (Li,K,Na)(Nb,Ta)O-3 (abbreviated as LKNNT-AS) lead-free piezoelectric ceramics with an optimized composition endowed with a state of two-phase coexistence. A small amount (0.1wt%) of MnO2 can significantly further enhance the piezoelectric property of LKNNT-AS ceramics, whose piezoelectric constant d(33) and converse piezoelectric coefficient d(33)* as well as planar electromechanical coupling factor k(p) reach 363 pC/N, 543pm/V, and 0.49, respectively. The temperature stability of piezoelectricity in MnO2-modified LKNNT-AS samples also improved, which is associated with the more uniform and better thermally stable ferroelectric domains that were revealed by piezoresponse force microscopy.
