Development of Textured Perovskite Ferroelectric Materials

Xiao Jing;Sun Xiaoqin;Liu Hanxin;Ouyang Shixi Stat. Key Lah of Advanced Technology for Materials Synthesis and Processing,Wuhan University of Technology, Wuhan 430070  
The types and the development of piezoelectric/ferroelectric materials were introduced briefly in this paper. The differences in the properties and fabrication methods between the piezoelectric ceramics and single crystals wrer compared, which indicate that the fabrication of textured piezoelectric ceramics is necessary. Taking the perovskite PMN-PT ceramic as an example, an easy and effective way to form the textured structure templated grain growth (TGG) was proposed. The methods to fabricate the PMN-PT powder and the templated materials as well as the method to align the template were analyzed. The achievements obtained so far, the future work and application prospect were presented.
