The pyroelectric effect is extensively used in infrared imaging, detection systems, military equipment, and smart furniture, which require pyroelectric materials to simultaneously possess a high pyroelectric coefficient () and a high Curie temperature () for circuit integration. However, the of commercial lead zirconate titanate (PZT) is limited to 230 °C, imposing an insurmountable challenge in the integration. Here, we investigated the pyroelectricity in NaBiTiO (NBT) with a high Curie temperature (∼660 °C), meeting the temperature requirements for integration. Textured NBT ceramics with a high degree of orientation (80%) were fabricated by using tape-casting, resulting in a of 122 μC m K, a 144% improvement over randomly oriented NBT ceramics. This method was also applied to doped NBT ceramics (NBTM-5Nb), achieving an impressive of 252 μC m K, representing a 400% improvement compared to randomly oriented NBT ceramics. Meanwhile, the textured NBTM-5Nb ceramics exhibit excellent figures of merit with = 1.05 × 10 m V, = 0.09 m C, = 4.9 × 10 Pa, comparable to the performance of PZT. Furthermore, the textured ceramics exhibit excellent thermal stability, with no performance degradation after annealing at 300 °C, rendering them suitable for circuit integration.

The solid-state reaction technique was employed to synthesize lead-free ceramics, specifically (1-x-y)(NaBi)TiO-xBaTiO-y(KBi)TiO. For attaining a pure perovskite phase, it was found that the optimal calcination temperature is 1000 °C, maintained for a duration of 4 h. Through X-ray diffraction (XRD) analysis, the morphotropic phase boundary (MPB) was detected in (1-x-y)NBT-xBT-yKBT ceramics for certain molar compositions, specifically in 0.

Article Synopsis
- The study explores the mechanical properties of Mn- and Fe-doped NaBiTiO ceramics, measuring factors like Young's modulus, Poisson's ratio, and more, in both unpoled and poled states.
- Results indicate that adding Mn and Fe ions and applying electric poling improve the ceramics' mechanical and piezoelectric properties, altering their stress-strain responses.
- These modifications lead to significant ferroelastic deformation and large remnant polarization, suggesting that these doped ceramics could serve as effective alternatives to PZT ceramics in high-stress actuator applications.

Dielectric ceramics possess a unique competitive advantage in electronic systems due to their high-power density and excellent reliability. NaBiTiO-based ceramics, one type of extensively studied energy storage dielectric, however, often experience A-site element volatilization and Ti reduction during high-temperature sintering. These issues may result in increased energy loss, reduced polarization and low dielectric breakdown electric field, ultimately making it challenging to achieve both high energy storage density and efficiency.
