The widely used piezoelectric Pb(Zr{sub 1-x} Ti{sub x})O{sub 3} ceramics have been known to have Zr{sup 4+} and Ti{sup 4+} randomly distributed on the B-site lattice in the ABO{sub 3} perovskite structure. In this study, we attempted to develop long range 1:1 B-site cation order by forming the solid solution of (1?x)Pb(Mg{sub 1/2}W{sub 1/2})O{sub 3} - xPb(Zr{sub 0.5}Ti{sub 0.5})O{sub 3} (x {ge} 0.60). High temperature X-ray diffraction tests indicate that the cation order is embedded in the structural order. The solid solution ceramics appear to have a non-cubic paraelectric phase above their Curie temperatures. The competition between the antiferroelectric order in Pb(Mg{sub 1/2}W{sub 1/2})O{sub 3} and the ferroelectric order in Pb(Zr{sub 0.5}Ti{sub 0.5})O{sub 3} leads to the relaxor ferroelectric behavior in the solid solution. Since the temperature at dielectric maximum, T{sub m}, is significantly above room temperature, regular polarization versus electric field hysteresis loops are recorded in these compositions at room temperature. In addition, these ceramics show very good piezoelectric properties.
