    The Ba2+ additions antiferroelectric ceramics with compositions far from the morphotropic phase boundary show slim-loop hysteresis. The phase transition electric-field lower to 1.5kV/mm, the hysteresis of electric-field reduces to 0.2kV/mm. The shape of hysteresis loop is slanted, and the polarization nearly increases linearly with the increasing of electric-field. The magnitude of strain is easy to control by the applied electric-field, and it is desired for other applications.
