“…To date, however, lead zinc tungstate Pb(Zn 1/2 W 1/2 )O 3 (PZW, a zinc-analog of PMW) of a perovskite structure has not been synthesized. Phase developmental results on PbO + (Zn 1/2 W 1/2 )O 2 could only be found [4], where mixed phases of Pb 2 WO 5 and ZnO were only reported, instead of the desired perovskite. Compared with PMW, the inability in the perovskite formation in PZW can be attributed to the smaller electronegativity difference (END [5]) of 1.8 in Zn-O, whereas the value in Mg-O is 2.2.…”

“…This decomposition phenomenon was also reported in a previous attempt to synthesize PZW. 7 The superlattice peak such as (1/2, 1/2, 1/2), was also observed from x = 0% to 30%, indicating the strong ordering between B-site (Mg 2+ , Zn 2+ ) and B'-site (W 6+ ) ions.…”

New Antiferroelectric Solid Solution of Pb(Mg_1/2W_1/2)O₃–Pb(Zn_1/2W_1/2)O₃ as Dielectric Ceramics

et al. 2014

A new solid solution of (1−x)Pb(Mg1/2W1/2)O3–xPb(Zn1/2W1/2)O3 has been prepared in the form of ceramics by solid‐state reaction with composition x up to 30%. It is found that with the substitution of Zn2+ for Mg2+ on the B site of the of complex perovskite structure the antiferroelectric (AFE) Curie temperature TC of PMW increases from 40°C (x = 0) to 67°C (x = 30%), indicating an enhancement of antiferroelectric order, whereas, at the same time, the phase transition becomes more diffuse due to a higher degree of chemical inhomogeneity. X‐ray diffraction analysis indicates that the crystal structure adopts an orthorhombic space group (Pmcn) with a decrease in lattice parameter a, but an increase in b and c as the Zn2+ concentration increases. The low dielectric constant (~ 102), low dielectric loss (tanδ ≈ 10−3), linear‐field‐induced polarization, and significantly high breakdown field (~ 125 kV/cm) at room temperature make this family of dielectric materials a promising candidate for ceramic insulators.

“…It should be noted that perovskite Pb(Zn1/2W1/2)O3 can only synthesized under high pressure [10]. The conventional solid state reaction method invariably leads to the mixture of Pb2WO5 and ZnO [11]. To the authors' knowledge, the complex perovskite Pb(Zn1/2W1/2)O3 has not been reported in literature to be incorporated into Pb(Zr1-yTiy)O3 for solid solutions.…”

The morphotropic phase boundary and electrical properties of (1 − x)Pb(Zn1/2W1/2)O3–xPb(Zr0.5Ti0.5)O3 ceramics

Ceramics in the solid solution of (1-x)Pb(Zn1/2W1/2)O3-xPb(Zr0.5Ti0.5)O3 system, with x = 0.80, 0.85, 0.90 and 0.95, were synthesized with the solid-state reaction technique. The perovskite phase formation in the sintered ceramics was analyzed with X-ray diffraction. It shows that the rhombohedral and the tetragonal phases coexist in the ceramic with x = 0.90, indicating the morphotropic phase boundary (MPB) within this pseudo-binary system. Dielectric and ferroelectric properties measurements indicate that the transition temperature decreases while the remanent polarization increases with the addition of Pb(Zn1/2W1/2)O3. In the composition of x = 0.85 which is close to the MPB in the rhombohedral side, a high piezoelectric property with d33 = 222 pC/N was observed.
