N2 - New morphotropic phase boundary (MPB) compositions with relatively high Tcs were projected in Pb(In1/2Nb1/2)O3–Pb(Sc1/2Nb1/2)O3–PbTiO3 (PIN–PSN–PT) solid solution based on the perovskite tolerance factor, and were experimentally confirmed. The phase structure, dielectric, pyroelectric, piezoelectric and ferroelectric properties of PIN–PSN–PT ceramics were investigated. The rhombohedral–tetragonal phase transition temperatures Tr-t on the order of 189–210 °C, Curie temperatures Tc on the order of 274–285 °C and piezoelectric coefficients d33 in the range of 310–360 pC/N, were achieved in xPIN– (1 − x)PSN–0.37PT (x = 0.15–0.23) ceramics, demonstrating a promising relaxor–PbTiO3 system with high phase transition temperatures. In addition, the maps of Tc, Tr-t, d33 and εr with respect to composition were established, based on which, a clear direction for composition screening in future crystal growth of the PIN–PSN–PT system was given.
