Abstract:

以叔丁醇为溶剂和成孔模板,采用冷冻–干燥工艺制备1–3型多孔锆钛酸铅(leadzirconatetitanate,PZT)陶瓷,采用凝胶注模工艺制备3–3型多孔PZT陶瓷,利用扫描电子显微镜和压汞仪对多孔陶瓷的形貌和孔径分布进行表征,利用阻抗分析仪测试多孔陶瓷的介电常数,利用Piezo–metersystem测量仪测试样品的压电性能。结果表明相比于3–3型多孔PZT陶瓷,在初始浆料固含量相同的条件下,1–3型多孔PZT陶瓷具有更高的气孔率;而气孔率相当时,1–3型多孔PZT陶瓷的压电系数比3–3型样品高出20%以上,介电常数高出1倍左右,且最低的声阻抗已达到2.1×107(Pa?s)/m,明显低于3–3型样品并与生物组织和水的声阻抗值非常接近。
