研究了用电泳沉积（EPD）法制备PZT厚膜。以磷酸酯（PE）为分散剂，制备了纳米PZT粉体在乙醇中的胶体悬浮液。通过测量悬浮液的pH值、电导率、沉积重量和PZT绿色压坯的相对密度，研究了PE添加量对PZT悬浮液稳定性的影响。施加电压对相对绿色密度的影响也被确定为PE重量%的函数。采用XRD和SEM对烧结PZT陶瓷的成分和显微结构进行了表征。研究了PZT陶瓷的电学性能。
The formation of thick PZT films via electrophoretic deposition (EPD) was studied. The colloidal suspension of a nano-sized PZT powder dispersed in ethanol was prepared using a phosphate ester (PE) as a dispersant. The amount of PE addition on the stability of the PZT suspension has been investigated by measuring the pH and conductivity of the suspension, deposition weight and the relative density of the PZT green compacts. The effect of the applied voltage on the relative green density was also determined as a function of the wt% PE. The composition and microstructure of the sintered PZT ceramics were characterized by XRD and SEM. The electrical properties of the PZT ceramics were also investigated.
