WebOct 31, 2024 · Here, we investigated the antiferroelectric-ferroelectric phase transitions in polycrystalline NaNbO3, a material recently suggested as the basis for lead-free antiferroelectrics with high energy storage densities. An irreversible transition from the antiferroelectric state to a new state showing macroscopic piezoelectricity (d33=35 pC/N) … WebThe stability of the ferroelectricity and piezoelectricity in the NN ceramic was evaluated. 2. Experimental Procedure Raw materials, Na 2CO 3 and Nb 2O 5, were mixed in the ... The grain size of the NN ceramic is about 3–5mm. The phases in the calcined NN powder and the sintered ceramic were analyzed by powder X-ray diffraction (XRD)
Grain-size-induced ferroelectricity in NaNbO3

WebMar 30, 2024 · As an actively studied lead-free antiferroelectric (AFE) material, NaNbO 3 has long suffered from its ferroelectric (FE)-like polarization-electric field ( P - E) hysteresis loops with high remnant... WebAbstract. A (001)-oriented NaNbO 3 –LaCoO 3 :Mn thin film with enhanced ferroelectric properties was successfully deposited on a SrRuO 3 -buffered LaAlO 3 substrate by … WebApr 8, 2024 · The grain size distribution analyzed by Nano Measurer is shown in the inset of Fig. 2 a–d. It is obvious that with the introduction of BS, the grain size distributed becomes more uniform, especially for x = 0.10 sample. From statistical point of view, the average grain size decreases from 0.67 μm to below 0.6 μm with increasing the BS level. how to start over at 67
