Here, we propose a grain engineering approach to decouple this property conflict by directly designing the microstructure of BNT-based ceramics at the morphotropic phase boundary. Rather than relying on complex chemical modifications, grain morphology is modulated to regulate the ferroelectric-to-relaxor transition. The optimized ceramic exhibits a d33 of \u223c180 pC\/N, a coercive field Ec of 23.6 kV\/cm, a remnant polarization Pr of 34.5 \u03bcC\/cm2, and a depolarization temperature (Td) of 125 \u00b0C, while maintaining less than 2% variation in d33 from 30 to 110 \u00b0C. This temperature-insensitive d33 originates from grain-engineered multiphase coexistence, which maintains a high piezoelectric response while stabilizing the field-induced long-range ferroelectric order against thermal depolarization. These findings highlight grain engineering as a robust microstructural strategy for developing high-performance, temperature-stable lead-free piezoceramics, paving the way for their use in high-precision devices under fluctuating thermal environments.<\/jats:p>","DOI":"10.1021\/acsami.6c12631","type":"journal-article","created":{"date-parts":[[2026,9,27]],"date-time":"2026-09-27T19:01:44Z","timestamp":1790535704000},"page":"53604-53616","source":"Crossref","is-referenced-by-count":0,"title":["Grain Engineering Modification of Temperature-Insensitive High Piezoelectricity in Bi0.5Na0.5TiO3-Based Ceramics at Morphotropic Phase Boundary"],"prefix":"10.1021","volume":"18","author":[{"given":"Huihui","family":"Liu","sequence":"first","affiliation":[{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]},{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4777-9093","authenticated-orcid":true,"given":"Yiping","family":"Wang","sequence":"additional","affiliation":[{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Chen","sequence":"additional","affiliation":[{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]},{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junhong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110819"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Xia","sequence":"additional","affiliation":[{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]},{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Yang","sequence":"additional","affiliation":[{"name":"Nanjing University of Aeronautics and Astronautics , , ,","place":["Nanjing, China, 210016"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,27]]},"reference":[{"key":"2026100705070648900_cit1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmatsci.2021.100836","article-title":"Phase structure and properties of sodium bismuth titanate lead-free piezoelectric ceramics","volume":"122","author":"Zhou","year":"2021","journal-title":"Prog.
