The composite piezoelectric ceramics with periodical ferroelectric domains were prepared by traditional composite technology, and the bulk ceramics with periodical ferroelectric domains were produced by a periodically poling method. The thicknessshear resonance and frequency properties of those two kinds of periodical ferroelectric domain ceramics were investigated. It is concluded that periodical ferroelectric domain structure can effectively restrain the bad effect from longitudinal or radical high order harmonious oscillation, and thickness shear resonance frequency can be increased by the periodically poling method, therefore the piezoelectric ceramics with inductance characteristics could be produced by the method of resonance and antiresonance at some frequency region through adjusting the size of periodical ferroelectric domain.
