摘要
A series of Pb<sub>1-x</sub>Ni<sub>x</sub>TiO<sub>3</sub> (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 d<sub>33</sub> of the nanocomposite Pb<sub>1-x</sub>Ni<sub>x</sub>TiO<sub>3</sub> prepared by co-precipitation method is higher than those of the prepared by general ceramic method. The coupling factor k<sub>p</sub> increased by the more doping of Ni. The ultrasonic wave velocity decreased also with increasing Ni contents. The polarized nano-sample of composition Pb<sub>0.5</sub>Ni<sub>0.5</sub>TiO<sub>3</sub> is suitable for improving application of useful piezoelectric technology.
