- •
We first reported the domain patterns of Bi0.5(Na0.78K0.22)0.5TiO3 ceramics.
- •
TEM images exhibited the difference of domain width between poled and unpoled sample.
- •
The crystal structures of the lamellar domains were determined to be P4bm.
- •
The poling induced domain growth and enhanced the stability of ferroelectricity.
