摘要：

Pb[(Sc1/2Nb1/2)(0.575)Ti-0.425]O-3 (PSNT) was prepared by the two-step calcining method. The sintering conditions for PSNT ceramics were investigated in the temperature range of 1200 to 1300 degrees C. The density of PSNT fired at 1300 degrees C was 7.5 g/cm(3), which Res in the range of 93% of the theoretical value, The dielectric constant and tan delta were 1760 and 0.022, respectively. The pyroelectric coefficient of this ceramic sample was 50 nC/cm(2) K, which is larger compared with other well-known pyroelectric materials. The spontaneous polarization P-s calculated by the pyroelectric current method showed a typical diffuse phase transition and its value was 28 mu C/cm(2) at room temperature. Large coupling factors of k(p)=51% and k(t)=53% were obtained.
