Application of Texture Techniques to Enhanced Lead-free Piezoceramics

Recently, texture technique, which is an effective method to improve the piezoelectric properties of Lead-free ceramics, has been widely investigated and attracted much attention. In this paper, several texture techniques, such as hot processing, oriented consolidation of anisometric particles, templated grain growth, reactive templated grain growth and multi-layer grain growth techniques, and along with their development and applications to Lead-free piezoceramics, are reviewed. The influences of texture processing on microstructure and grain growth mechanisms of textured ceramics are discussed in detail.
