摘要

摘要: 采用常规的氧化物陶瓷生产工艺与多孔化技术相结合的方法，制作出不同密度的PZT-95/5陶瓷样品，进行流体静压相变实验。研究发现，陶瓷材料的铁电-反铁电相变与陶瓷中气孔的存在有密切的关系，运用气孔塌陷假设或者边缘剪切假设可以对此现象进行定性解释，研究结果与美国圣地亚实验室的相似研究结果一致。

Abstract: The phase transformation of PZT-95/5 ceramics with low density under hydrostatic pressure were investigated experimentally. Experimental results show that ferroelectric to antiferroelectric phase transformation is closely related to pores in ceramics. Pore-collapse theory or Lateral-shear-stress hypothesis gives a qualitative illustration for the results. All the experimental results correspond to those given previously.
