Templated grain growth and enhanced strain of PIN-PMN-PT textured ceramics

Grain-oriented growth enabled by aligned template seeds stands as the cornerstone for developing advanced textured ferroelectric ceramics. In this work, the templated-grain-growth behavior and corresponding electric properties of [001]-textured PIN-PMN-PT ternary ferroelectric solutions with high PIN content were investigated systematically. Pronounced grain-oriented-growth was achieved as PIN content within 45 mol%, while texturing development was significantly constrained in ceramics with a PIN content exceeding 50 mol%. The failure of highly-texturing could be attributed to the excessive lattice mismatch between BaTiO 3 templates and PIN-PMN-PT matrix. Concurrently, higher PIN content contributed to enhanced piezoelectric response in PIN-PMN-PT textured ceramics under high electric field loading. The highly [001]-textured PIN-PMN-PT ceramics with F 001  > 96% revealed remarkably high strain S m  > 0.40% accompanied by ultra-low strain hysteresis H s  ∼ 6.0%.
