High Piezoelectricity and Strong Field Endurance in Pb(Zr,Ti)O 3 ‐Rich Textured Ceramics

Abstract Simultaneously achieving ultrahigh piezoelectricity (including high piezoelectric constant d 33 and strain) along with enhanced field endurance (characterized by high coercive field E C and Curie temperature T c ) is critical for high‐drive electromechanical applications. However, this remains a major challenge, as high piezoelectricity typically arises from an easy polarization rotation enabled by low ferroelectric anisotropy, while strong thermal/stress/electric field endurance requires high anisotropy. Here, a multifaceted design strategy is proposed that combines structural distortions and crystallographic anisotropy. This approach is successfully demonstrated in Pb(Yb 1/2 Nb 1/2 )O 3 (PYN) modified and [001] textured PbZr 1‐ x Ti x O 3 (PZT)‐rich ceramics via a one‐step templated grain growth method. As a specific representative, 0.5% Eu‐doped 0.1PYN ‐0.9PZT textured ceramics, shows an outstanding d 33 of 950 pC N −1 and d 33 * of 1927 pm V −1 , an ultrahigh strain of 0.65%, a large E C of 10 kV cm −1 , and a high T C of 360 °C. High‐resolution electron microscopy and phase‐field simulations confirm that these high performances originate from the synergistic design of a highly distorted matrix (via PYN incorporation), local structural heterogeneity induced by Eu‐doping, and crystallographic anisotropy achieved through texturing. This study successfully offers a cost‐effective new route for the design of ultrahigh piezoelectricity and enhanced field endurance piezoceramics.
