A region of dielectric dispersion was found in ferroelectric lead titanate zirconate ceramics at frequencies about 1 Gc, The losses associated with the dispersion are quite high, the dissipation factor rising to about 0.4 at 2 Gc. The magnitude of the dispersion is halved in the measured frequency range 500 Mc to 2 Gc by electrical orientation (poling) of the ceramic. Two mechanisms that may account for the effect, inertial clamping of the piezoelectric response of ferroelectric domains and clamping of domainwall motion, are discussed.
