| Popis: | In this study, BNBT-KNN-xTa2O5 was designed and synthesized, successfully achieving a reduction in the relaxor-ferroelectric phase transition temperature. Synergy between temperature-dependent ferroelectric testing and dielectric spectroscopy confirmed that the depoling temperature gradually decreased with increasing doping concentration. Fitting of the relaxation parameter and freezing temperature substantiated that the incorporation of Ta2O5 increased the degree of relaxation in BNBT-KNN-xTa2O5, thereby effectively lowering the relaxor-ferroelectric phase transition temperature. |
