Title: Behavior of Templates during Texturing of Piezoceramics
Abstract: 

Texture engineering has attracted significant attention as a promising process for improving not only lead-free piezoelectric ceramics but also lead-based piezoelectric ceramics. Generally, texturing process consists of synthesis of plate-like templates, aligning of templates in the matrix particles using tape-casting or screen printing process, and growth of templates by consuming matrix particles during sintering. Depending on the chemical composition and crystal structure of the template and matrix used, texturing process can be classified into three categories: Templated grain growth (TGG), reactive-templated grain growth (RTGG), and hetero-templated grain growth (HTGG). One of the most important parameters in texture engineering is the behavior of templates during calcination and/or sintering. In this study, the role and behavior of templates in texturing of lead-based and lead-free piezoelectric ceramics were investigated.
