The dielectric and the relaxor properties of solid-solution (1-x)Pb(Mg1=3Ta2=3)O3-xPbZrO3 were
studied as functions of PbZrO3, and the stability of the perovskite phase was studied as a function of
the sintering temperature. The dielectric constant and the spontaneous polarization of poled samples
were measured. The addition of PbZrO3 aects the phase transitions of the Pb(Mg1=3Ta2=3)O3
system, and the transition temperature is continuously shifted to higher temperature by adding a
small amount of PbZrO3. Composite materials with the perovskite structure have been identied
to have a high dielectric constant and spontaneous polarization. The value of the diuseness parameter
decreased as the amount of PbZrO3 increased, indicating a less broad phase transition.
Compositions with PbZrO3 in the range 0.1 x 0.6 also showed a diuse phase transition.
