dc.description.abstractPerovskite (Pb(1-3x/2) Bi<inf>x</inf>)(Zr(1-3<inf>x/4</inf>) Yb<inf>x</inf>)O<inf>3</inf> (PZ-BY) ceramics, where x = 0.01-0.10, were synthesized by conventional solid state reaction. The effect of BiYbO<inf>3</inf> on crystal structure, phase transitions and electrical properties was studied as a function of composition. The X-ray diffraction (XRD) result indicated that the perovskite structure with orthorhombic symmetry was a major phase for all samples. The pyrochlore phase, identified as Yb<inf>0.2</inf>Zr<inf>0.8</inf>O<inf>1.9</inf>, coexists in PZ-BY ceramics. The influence of instability and a small tolerance factor (t) and the average electronegativity difference () of pure BY on phase formation of PZ-BY ceramic has been discussed. Furthermore, it was found that adding small tolerance factor BiYbO<inf>3</inf> compound can stabilize the antiferroelectric (AFE) phase of PZ solid solutions and decreasing t of solid solution can enhance Curie temperature of PZ.
