Ferroelectricity in intergrowth Bi₃TiNbO₉–Bi₄Ti₃O₁₂ ceramics

Yi, Z. G.; Wang, Y.; Li, Y. X.; Yin, Q. R.


Monophase intergrowth Bi₃TiNbO₉–Bi₄Ti₃O₁₂ (BTN-BIT) ceramics were synthesized by solid-state reaction method. In the temperature dependence of dielectricpermittivity, two anomalies appeared at 945 and 1114K, respectively. The ferroelectric hysteresis loop measurement revealed that the 2Pr is 20μC/cm², nearly as twice as that of the BTN ceramic. The crystal structure analysis indicated that the enhanced octahedral distortion along the a axis is the main contribution to the ferroelectricity of...[Show more]
