摘　　要：采用压制成型法,首次以快硬早强的硫铝酸盐水泥为基体制备了水泥基压电复合材料。详细阐述了水泥基压电复合材料的制备过程;通过实验确定了适宜的极化条件,分析讨论了极化过程中出现漏电流的原因,并提出了一些初步的解决途径。结果表明,对硫铝酸盐水泥基压电复合材料来说,适宜的极化工艺参数:极化电场强度为4kV/mm,极化时间为45min,极化温度应低于130°C。The sulphoaluminate cement was, for the first time, used to fabricate 0-3 piezoelectric composites by compressing technique. The optimum poling conditions were obtained. The reasons of the leakage current in the course of the poling were discussed,and the approach of solving these problems were put forward. The results show that The optimum poling field, poling time and poling temperature are 4.0 kV/mm, 45 min and 130 °C respectively.
