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.
