Crystallographic texture engineering through templated grain growth (TGG) has gained prominence as a highly effective strategy for optimizing the electromechanical performance of lead-free piezoelectric ceramics, offering pathway toward sustainable alternatives to lead-based systems like lead zirconate titanate (PZT). By achieving high degrees texture, with Lotgering factors (LFs) often exceeding 90%, these have demonstrated properties that rival or even surpass their counterparts. Despite advancements, field lacks comprehensive understanding how specific template parameters influence quality and functional across different material systems. This review provides an in-depth analysis morphology, composition, crystallographic orientation on texturing key systems, including BaTiO3 (BT), (K0.5Na0.5)NbO3 (KNN), Bi0.5Na0.5TiO3 (BNT). Furthermore, it explores selection affects induced direction, this impacts material’s phase structure domain configurations, ultimately influencing dielectric properties. consolidating existing knowledge identifying current challenges, work highlights strategies in providing essential insights future research aimed at advancing high-performance, environmentally friendly materials applications such sensors, actuators, energy-harvesting devices.

Abstract High mechanical quality factor ( Q m ) and low loss are crucial for the performance of piezoelectric materials in high‐power applications. Although potassium sodium niobate (KNN) based ceramics promising candidates lead‐free due to their favorable environmental benefits, they traditionally face a trade‐off between high coefficient d 33 . To address this long‐standing issue, multivalent acceptor codoping strategy is presented that innovatively induces hierarchical domain structure hard‐type KNN‐based piezoceramics, significantly increasing wall density pinning strength while maintaining well‐ordered ferroelectric structure, thereby achieving simultaneous enhancement , thermal stability. The optimized composition possesses up 948 with 132 pC/N, representing improvements 80% 25% compared Cu‐doped samples, outstanding > 800, 130 pC/N across broad temperature range 25–175 °C. Furthermore, our sample retained under conditions, outperforming several commercial lead‐based ceramics. These results provide new insights into defect‐domain interaction demonstrate potential

Piezoelectric ceramics have the advantages of uniform composition, excellent performance, good electromechanical coupling and high cost performance. They are currently one important materials for manufacturing sensors semiconductor components on market. Although piezoelectric ceramic widely used because their many advantages, how to improve properties is still a hot difficult research spot. Previously, were affected by adjusting grain size, but due its limited enhancement effect, researchers hope find other ways more efficiently. Research has found that texture process can enable isotropic obtain similar characteristics single crystals exhibit anisotropy. This greatly improves ceramics. During process, type content template, degree orientation, factors will significantly affect textured With continuous development technology been improved, practical application less. Based this, this article expounds design principles ceramics, summarizes progress in preparation systematically explains importance template orientation selection processing. Finally, paper also analyses looks forward optimization methods prospects It hoped help

The macroscopic properties of piezoelectric materials can be profoundly influenced by stress. In this research, thermodynamic potential parameters K0.4Na0.6NbO3 (KNN) single crystals have been experimentally quantified to assess the effects Leveraging Landau theory, it has identified that application biaxial tensile stress causes a significant elevation in both property and phase transition temperature KNN crystals. This remarkably extends their working range improves material's applicated potential. coherence between these computational outcomes experimental data—from strategic growth with internal stress—underscores reliability our findings (dielectric constant from 213 1274, TO-T 180 234 °C). Additionally, theoretical calculation predicts enhancement capabilities study provides valuable insights for high-quality further promotes lead-free materials.
