摘要: For NaNbO3, its intrinsic phase transition sequence is still controversial in literature. In this paper, high-densified NaNbO3 ceramics derived from mechanochemical nanostructures presented a stabilized antiferroelectric characteristic. addition to the Tc of 360 °C, another diffuse dielectric anomaly appeared around 100 °C, which did not vanish after O2 annealing treatment. The fine structure analysis indicated that belongs first order P Q phase. Moreover, even exerting strong electric field close breakdown value, normal ferroelectric loops cannot be induced, proving large free energy difference between these two phases.
