“…This scenario might be due to higher crystalline deformation than other materials, which can be seen. 53 The porosity of the samples, which is opposite of the solidity, was on the scale of 24 to 28%, whereas the ceramic powder BMT− BFO showed the minimum porosity (24%).…”

“…Furthermore, the estimated residual polarization ( P r ) in the pC/NCm 2 unit (Figure right scale) also changed following the analogous trend of the piezo constant. Because of M/R-T phase coexistence, more contributing polarization states might occur even at room temperature, which leads to the higher d 33 by polarization rotation . However, the fundamental lattice variance as well as external (domain flipping and phase border moves) effects with increased temperature are responsible for the net enhancement of piezoelectric characteristics, which results in a rise in piezoelectric characteristics.…”

In this study, lead-free BiM 2+ (Zn, Ca, Mg)Ti−BiFeO 3 ceramics are fabricated under eco-friendly hydrothermal reaction conditions at 250 °C. XRD patterns show that all the synthesized compounds exhibit a phase coexistence of monoclinic and tetragonal perovskite-type structures with a morphotropic phase boundary at x = 0.4, with minimum impurity. The calculated average crystallite/grain size of the samples was close to 50 nm at full width at half-maximum of the main peak. The corresponding bonds of the constituent elements were observed by FTIR analysis, which further supports the formation of the local structure. EDS analyses detect all of the elements, their quantities, and compositional homogeneity. SEM data show agglomerated and nearly spherical morphology with an average particle size of about 128 nm. All synthesized ceramic powders revealed thermal stability with trivial mass loss up to investigated high temperatures (1000 ο C). The dielectric constant reached its maximum at 38.7 MHz and finally remained constant after 80 MHz for all nanoceramics. Because of the complementary impact of different compositions, the most effective piezoelectric characteristics of d 33 = 136 pCN −1 , P r = 8.6 pCN −1 cm −2 , and k p = 11% at 30 °C were attained at x = 0.4 content for 0.4BiCaTi−0.6BiFeO 3 ceramic. The measured magnetic hysteresis data (M−H curve) showed a weak ferromagnetic nature with the highest moment of ∼0.23 emu/g for 0.4BiCaTi−0.6BiFeO 3 , and other samples exhibited negligible ferromagnetic to diamagnetic transition. The optical response study shows that the 0.4BiMgTi−0.6BiFeO 3 sample yielded the maximal transmittance (50%), whereas the 0.4BiCaTi−0.6BiFeO 3 compound exhibited the highest refractive index. The calculated large band gap shows a high insulating or dielectric nature. Our findings demonstrate that the BiM 2+ Ti− BiFeO 3 system, which was fabricated using a low-temperature hydrothermal technique, is an excellent lead-free piezoelectric and multiferroic nanoceramic.
