We observe a larger electrocaloric response for the template-free ceramics compared to 7 and 10 wt% template containing ones, suggesting that grain orientation along rhombohedral < 100 > does not improve the electrocaloric response. Indirect measurements yielded a large adiabatic temperature change of around 3 K under an electric field of 50 kV/cm, which is significantly higher than 0.9 K reached at a lower electric field of 40 kV/cm using the direct measurement.eninfo:eu-repo/semantics/closedAccessSodium bismuth titanateElectrocaloric effectGrain orientationTemplated grain growthTape castingArticle2-s2.0-8517967468510.1016/j.jeurceramsoc.2023.11.042
