摘　　要：A series of Pb_1-xNi_xTiO₃ (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) were prepared by the general ceramic and co-precipitation method. The grain size decreased with increasing Ni contents. The piezoelectric modulus d33 increased with increasing Ni contents. It was observed also the d₃₃ of the nanocomposite Pb_1-xNi_xTiO₃ prepared by co-precipitation method is higher than those of the prepared by general ceramic method. The coupling factor k_p increased by the more doping of Ni. The ultrasonic wave velocity decreased also with increasing Ni contents. The polarized nano-sample of composition Pb_0.5Ni_0.5TiO₃ is suitable for improving application of useful piezoelectric technology.A series of Pb_1-xNi_xTiO₃ (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) were prepared by the general ceramic and co-precipitation method.
