- Abstract
The sulphoaluminate cement was, for the first time, used to fabricate 0-3 piezoelectric composites by compressing technique. The dependences of piezoelectric properties of composites on poling conditions, particle size and contents of Lead Zirconate Titanate (PZT) were discussed especially. The results show that the piezoelectric properties of composites are improved by increasing poling field E, poling time t and poling temperature t. The optimum E, t and Tare 4.0 kV/mm, 45 min and 120°C respectively in this work. The piezoelectric strain factor d33 is found to increase with increasing particle size of PZT. When the particle size of PZT is larger than about 130 μm, the d33 is nearly independent of particle size. The d33, g33 and the electromechanical coupling coefficient Kp, Kt of composites increase rapidly with increasing content of PZT. When the content of PZT reaches 85%, Kp and Kt are 28.54 and 28.19%, respectively.
