N2 - xPb(Sc1/2Nb1/2)O3–(1 − x)Pb(Hf1−yTiy)O3 piezoelectric ceramics were prepared by solid-state route, and the phase structures and piezoelectric properties of ceramics were systematically investigated. Results showed that the sample with the composition of x = 0.07 and y = 0.53 possessed higher phase coexistence between the rhombohedral and tetragonal, and exhibited the optimal properties among different constituent systems, i.e., TC = 355 °C, d33 = 400 pC/N, εr = 1390, and tan δ = 1.05%. Furthermore, the effects of temperature on d33, leakage current density, P-E loop, and unipolar strain were studied for xPb(Sc1/2Nb1/2)O3–(1 − x)Pb(Hf0.47Ti0.53)O3 samples. The sample with x = 0.07 revealed better temperature stability as well, the reason of which was analyzed in detail. The study indicates that the 0.07Pb(Sc1/2Nb1/2)O3–0.93Pb(Hf0.47Ti0.53)O3 piezoelectric ceramic has excellently comprehensive properties suitable for application in higher temperature condition.
